Half an alka seltzer tablet is dissolved and completely reacted in 25mL of HCL, and the gas produced displaces 0.240L of water from a secondary flask.

Alka Seltzer has 1904 mg of NaHCO3 per tablet (approx. 3.2grams each) Half a †ablet was used at 1.452g. V= 0.240Liters CO2 P (of the surrounding air in the room)= 0.980 Atm T (of gas) = 295 Kelvin Vapor pressure of water at 22 deg. C is 21 torr.

So here is what has to be found: I'm not entirely sure how to factor in water vapor, or get moles of CO2 without the mass of it.

1. Partial pressure of CO2 =_______

2. Solubility of CO2 in flask A= 20mL

3. Corrected volume of CO2=______

4. Moles of CO2=_________

5. Moles of NaHCO3 reacted=____

6.Mass of NaHCO3 reacted=____
