How to calculate vapor pressure

The density of acetone vapor in equilibrium with liquid acetone, (CH3)2CO, at 32 degrees Celsius is 0.876 g/L. What is the vapor pressure of acetone, in mmHg, at 32 degrees Celsius? (Use correct significant figures.)

Solution Preview

According To Gas Law:

P = d/M * RT

where P = pressure = ?
d = density = 0.876 g/L

Solution Summary

Gas Law expression P = d/M * RT can be used for the calculation of vapor pressure.
