A 1.00 L vessel contains 5 g N2 and 1.5 g H2O at 25 degrees C. Calculate the mass of LIQUID water that would be present in the vessel.
The vapor pressure of H2O at 25C is 23.8 mm Hg. Plug that into PV = nRT and solve for n = mols H2O vapor. Subtract from mols in the 1.5g initially present to find mols H2O liquid.
