Here's a general overview:
* At atmospheric pressure and room temperature (around 20°C or 68°F), the density of liquid propylene is approximately 0.514 g/cm³.
However, it's important to note:
* Temperature dependence: Density decreases as temperature increases.
* Pressure dependence: Density increases as pressure increases.
To get a precise value for the density of liquid propylene at a specific temperature and pressure, you would need to consult a specialized table or use a calculation tool that takes these factors into account.
