Calculate Mass of Water Vapor in NaHCO3 + HCl Reaction

AI Thread Summary
To calculate the mass of water vapor produced in the reaction between NaHCO3 and HCl, the total pressure must be determined, potentially using the equation P(total) = P(a) + P(b). The pressure of the room, given as 753.87 mm Hg, is relevant for this calculation. The ideal gas law may also be applied to find the mass of water vapor, given the number of moles (30.5 mol H2O). Clarification on the original question wording is needed for better understanding. Accurate interpretation of the provided data is essential for solving the problem effectively.

Homework Statement


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

Homework Equations





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.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
