The vapor pressure of water

Reference no: EM13718096

When solid CaCO3 is heated, it decomposes to give solid CaO and CO2 gas. A volume of 285mL of gas is collected over water at a total pressure of 730mmHg and 16 °C. The vapor pressure of water at 16 °C is 14 mmHg.
CaCO3(s)→CaO(s)+CO2(g)
What was the partial pressure of the CO2 gas and how many moles of CO2 gas were in the CO2 gas sample?
