Quick Answer
The liquid ethylene density calculator uses the generic density formula ρ = mass/volume. Enter mass in grams and volume in millilitres to get density in g/mL. A typical liquid ethylene reference value near its −103.7 °C boiling point is about 0.567 g/mL.
Density is mass divided by volume. For liquid ethylene, fifty six point seven grams in one hundred millilitres gives zero point five six seven grams per millilitre.
Key Takeaways
- Density equals mass divided by volume: ρ = m/V.
- With mass in grams and volume in millilitres, density is reported in g/mL.
- Liquid ethylene is about 0.567 g/mL near its −103.7 °C boiling point.
- Temperature and pressure must be recorded for precise liquid ethylene property work.
- The calculator returns 0 for invalid non-positive mass or volume inputs.

Formula
ρ = m / V
Where:
- ρ=Density(g/mL)
- m=Mass(g)
- V=Volume(mL)
Worked Examples
Liquid ethylene reference-like sample
A 56.7 g sample occupies 100 mL, matching the common liquid ethylene reference density near its boiling point.
- 1Use the density formula ρ = m / V.
- 2Substitute m = 56.7 g and V = 100 mL.
- 3Calculate ρ = 56.7 ÷ 100 = 0.567 g/mL.
Small ethylene aliquot
A 34.02 g portion in 60 mL gives the same density as the reference value.
- 1Start from ρ = m / V.
- 2Insert the measured values: ρ = 34.02 g ÷ 60 mL.
- 3The density is 0.567 g/mL.
Generic liquid sample
The same mass-over-volume relation works for any liquid when mass and volume use compatible units.
- 1Use ρ = m / V for a directly measured sample.
- 2Substitute m = 200 g and V = 250 mL.
- 3Calculate ρ = 200 ÷ 250 = 0.8 g/mL.
Introduction
This liquid ethylene density calculator applies the general density relationship ρ = mass ÷ volume using grams and millilitres. It is useful for checking a measured liquid sample, comparing cryogenic ethylene measurements, or converting laboratory observations into a density in g/mL. Liquid ethylene (ethene, C₂H₄) is commonly cited near 0.567 g/mL close to its normal boiling point of −103.7 °C, so the worked examples show how that value arises from simple mass and volume data. For solution-style concentration work, compare this result with the concentration calculator and molarity calculator.
What density means for liquid ethylene
Density tells how much mass is packed into each unit of volume. For liquid ethylene, density is usually reported for a specified low temperature because ethylene is a gas at ordinary room conditions and must be cooled or pressurized to remain liquid. A value near 0.567 g/mL is a practical reference around the boiling point, not a universal constant at every temperature.
Density in this calculator is reported in g/mL.
Mass must be entered in grams and volume in millilitres.
A larger mass in the same volume means a higher density.
A larger volume for the same mass means a lower density.
Density formula and units
The working equation is ρ = m / V, where ρ is density, m is mass, and V is volume. If mass is in grams and volume is in millilitres, the density automatically has units of g/mL. The same equation can be rearranged for planning measurements: m = ρV and V = m/ρ.
Keep the mass and volume conditions paired: the mass must belong to the exact sample volume you divide by.
Liquid ethylene reference value
Ethylene, also called ethene, has formula C₂H₄ and boils at about −103.7 °C at 1 atm. Data resources such as the NIST Chemistry WebBook and PubChem ethylene record are useful for checking identifiers, phase-change data, and safety context. Around the normal boiling point, a representative liquid density is approximately 0.567 g/mL.
Use the reference value as a reasonableness check; use measured temperature-specific data for engineering design.
How to calculate density step by step
Measure the sample mass, measure the corresponding liquid volume, then divide. For example, if 56.7 g of liquid occupies 100 mL, the density is 56.7/100 = 0.567 g/mL. This is the same arithmetic used for many liquids, from organic solvents to aqueous samples.
Tare the container before weighing the sample.
Record the liquid volume at the same temperature as the mass measurement.
Divide grams by millilitres.
Report density with suitable significant figures and temperature.
Why temperature matters
Liquid density changes with temperature because the volume of a fixed mass expands or contracts. Cryogenic liquids such as liquid ethylene are especially sensitive to handling conditions. The calculator intentionally uses the robust generic formula rather than a temperature correlation, so it remains testable and accurate for directly measured mass-volume pairs.
| Quantity | Effect on density | Practical note |
|---|---|---|
| Higher temperature | Usually lower density | Volume expands for the same mass |
| Lower temperature | Usually higher density | Volume contracts for the same mass |
| Two-phase sample | Unreliable value | Bubbles or vapor pockets inflate volume |
| Pressurized sample | Condition-specific | Record pressure with temperature |
Measurement accuracy and safety
Ethylene is flammable and cryogenic liquid handling requires appropriate equipment, ventilation, and trained procedures. Consult current safety documentation and use calibrated density or volume equipment. For terminology and unit conventions, see the IUPAC Gold Book density entry and the BIPM SI Brochure.

Common Values
⚠ Watch Out
- •Do not use room-temperature gas data as liquid ethylene density.
- •Record temperature because liquid density changes with thermal expansion.
- •Avoid two-phase samples; vapor bubbles make the measured volume too large.
- •Use appropriate cryogenic and flammable-gas safety procedures for ethylene.
- •Never divide by zero or by a volume that was not measured for the same sample.
Pro Tips
- →Tare the container before weighing the sample mass.
- →Use calibrated cryogenic-compatible volume equipment for low-temperature liquids.
- →Report density with temperature and pressure whenever possible.
- →Compare measured density with the 0.567 g/mL reference as a quick reasonableness check.
- →Keep significant figures aligned with the least precise mass or volume measurement.
FAQs
How do I calculate liquid ethylene density?
Divide the measured mass of the liquid sample in grams by its measured volume in millilitres. For example, 56.7 g divided by 100 mL equals 0.567 g/mL.
What is the reference density of liquid ethylene?
A commonly used reference value is approximately 0.567 g/mL near ethylene's normal boiling point of about −103.7 °C. Density changes with temperature and pressure, so use condition-specific data for design work.
Is ethylene the same as ethene?
Yes. Ethylene is the common name and ethene is the IUPAC name for C₂H₄, the simplest alkene.
Why does the calculator not ask for temperature?
This implementation calculates density from direct mass and volume measurements. A temperature correlation would require a validated property model and condition range, while mass divided by volume is universally testable.
Can I use this calculator for liquids other than ethylene?
Yes. If you enter mass in grams and volume in millilitres, the formula ρ = m/V gives density in g/mL for any homogeneous liquid sample.
What happens if volume is zero?
A zero or negative volume is physically invalid for this calculation, so the calculation function returns 0 rather than dividing by zero.
