A 27.8 liter container is initially evacuated, and then 8.8 grams of water is placed in it. After a time, all the water evaporates, and the temperature is 130.8 degrees C. Find the final pressure.

PV=nRT

P= nRT/V all you have to do is convert 8 grams water to moles water. tEmps in Kelvin

Ok thanks, so do you just find the molar mass of those 8 grams of water to find moles?
