Mass of water vapor

  1. 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.
