Problem 2.187
The saturated water vapour is enclosed in a cylinder under a piston and occupies a volume \(V_{0}=5.0 \mathrm{l}\) at the temperature \(t\) \(=100^{\circ} \mathrm{C} .\) Find the mass of the liquid phase formed after the volume under the piston decreased isothermally to \(V=1.61 .\) The saturated vapour is assumed to be ideal.
2.187. \(m_{l} \approx M p_{0}\left(V_{0}-V\right) / R T=2.0 \mathrm{~g}\), where \(p_{0}\) is the standard atmospheric pressure.
