1. The problem statement, all variables and given/known data
Find the mass of water vapor.
this is the reaction: NaHCO3+HCl-->NaCl+CO2+H2O

V=39.5 L
P=18.65 mm Hg
T=294 K
n=30.5 mol H20 (g)
pressure of room= 29.68 inHg=753.87mm Hg

2. Relevant equations



3. The attempt at a solution
Would i have to use this equation P(total)=P(a)+P(b)
and if so, would P(total) equal to the pressure of the room?
then after that would i have to use the ideal gas law?

What is the original wording of the question? Data - as you presented it - don't make much sense to me.
