Question

water has a vapor pressure of 23.76 torr at 25C if 1.15 g H2O is enclosed in a 1.0 L container will any liquid be present if so what is the mass of the water?

Answer 1

I would use PV = nRT and solve for n = number of moles H2O in the vapor phase. Compare this with moles H2O in 1.15 g. The difference, if any, will be the moles H2O in liquid form.
