Question
Data of Calcium Carbonate Analysis/Molar Volume of CarbonDioxide: Equation: CaCO3(s) + 2H3O+(aq) Ca2+ (aq) + 3 H2O(l)+ CO2(g) Mass of CaCO3 sample: 0.23 g Mass of CO2 generator and CaCO3sample before reaction: 47.74 g Initial volume of water of CO2 in a graduatedcylinder: 80 mL Final volume of water of CO2 in a graduatedcylinder: 71 mL Volume of CO2(g) collected : 0.009L (Sorry...I don't know if I calculated this partcorrectly.) Temperature of water : 18° C Barometrc pressure : 766 torr Vapor pressure H2O at 18°C :15.5 torr Mass of CO2 genator and CaCO3 sampleafter reaction: 47.76 g Mass loss of generator = mass of CO2 evolved :0.02 g (Sorry...I don't know if I calculated this partcorrectly.) 1) What is the pressure of "dry" CO2(g) in"torr"? 2) What is the pressure of "dry" CO2(g) in"atm"?

USEFUL EQUATION: P CO2 = PT - pH2O P CO2 = pressure of CO2 PT = total pressure pH2O = pressure of H2O (water vapor)Related Questions
