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.
 

1. What is the chemical equation for the NaHCO3 + HCl reaction?

The chemical equation for the reaction is NaHCO3 + HCl → NaCl + H2O + CO2.

2. How do you calculate the mass of water vapor produced in the reaction?

To calculate the mass of water vapor, first determine the moles of NaHCO3 and HCl used in the reaction. Then, use the mole ratio from the balanced chemical equation to find the moles of water vapor produced. Finally, use the molar mass of water (18.02 g/mol) to convert moles to grams.

3. What is the purpose of calculating the mass of water vapor in this reaction?

The mass of water vapor is important to know in order to understand the stoichiometry of the reaction and to determine the amount of water produced as a byproduct. It can also be used to calculate the percent yield of the reaction.

4. How does the amount of water vapor produced change if the amounts of NaHCO3 and HCl are varied?

The amount of water vapor produced is directly proportional to the amounts of NaHCO3 and HCl used in the reaction. This means that if the amounts of these reactants are increased, the amount of water vapor produced will also increase.

5. Are there any safety precautions to consider when conducting this reaction?

Yes, HCl is a strong acid and can cause burns if it comes into contact with skin. It is important to wear protective gloves and eyewear when handling HCl. Additionally, the reaction may produce carbon dioxide gas which can displace oxygen in a closed environment, so it is important to conduct the reaction in a well-ventilated area.
