A 0.276-g sample of a CaCO3 heterogeneous mixture was placed into a gas generator, the total mass of which is 87.719g (containing the CaCO3 sample and the beaker, an HCI solution, and test tubes is connected to a gas-collection apparatus. The following data were collected following the reaction.
Volume of wet CO2 37.7 mL
Temp of wet CO2 20.0 C
Pressure of wet CO2 770 torr
Mass of gas generator after reaction 87.642 g
a. Determine the mass and moles of CO2 evolved in the reaction. What is the mass difference of the gas generator?
b. Determine the pressure of the dry CO2.
c. Calculate the volume of the dry CO2 at STP.
d. What is the calculated molar volume of the dry CO2.
