24.5L of water vapour condenses into 18mL of liquid water??? Wtf >.<

18 mL of pure water is close enough to 18 g of water, i.e. 1 mol of water. Assuming all the water is converted to water vapour (i.e. gaseous water), 24.5 L of the gas would be produced at SLC (273.15 K and 101.325 kPa) and 22.4 L at STP, etc. The general gas equation can be used to determine the volume of gas that is equivalent to 18 mL water at any temperature and pressure. It can also be used to find the amount of liquid water into which a certain volume of gas will condense, given the temperature and pressure (and assuming 1 mL water = 1 g water).
