When solid CaCO3 is heated, it decomposes to give solid CaO and CO2 gas. A volume of 545 mL of gas is collected over water at a total pressure of 730 mmHg and 16 C. The vapor pressure of water at 16 C is 14 mmHg. CaCO3(s)→CaO(s)+CO2(g)

a. What was the partial pressure of the CO2 gas?

b. How many moles of CO2 gas were in the CO2 gas sample?
