use the ideal gas constant to calculate the number of moles of water vapor.
p=18.65 torr
v=39.5 L
r=0.08206
t=294 K

this is the equation im supposed to use right?
n= PV/RT


This is what i got.
n=(18.65)(39.5)/(0.08206)(294)=30.5 mol H20

but when i look it up online the answer is 0.04 moles of gas. am i right? if not what am i doing wrong?

You should convert 18.65 torr into atm.
