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.
