## Homework Statement

'Look up the density and vapour pressure of water at 25°C, and use the ideal gas law to calculate Vliq as a fraction of Vg for one mole of water at 25°C'

Ok so, Density of water at 25°C & 1atm is: 0.997 g/cm³.

The vapour pressure of water at 25°C and 1atm is: 3.1691 kPa

## Homework Equations

The ideal gas law: PV=nRT

Also, I think perhaps the Clausius-Claperon equation might be used?!

## The Attempt at a Solution

I think the question is a little ambiguous, so I am unsure of how to approach this question.

For a start, I can use the ideal gas equation to work out the volume of one mole of water vapour at 25°C and 1atm:

V=nRT/P= (1mole)x(8.314J/Mol.K)x(298K)/101,325Pa= 0.0245m³

However, I'm stuck now as to what is the next logical step!
