A 0.184 mol sample of a mixture of N2 as well as CO2 with a total pressure of 834torr was exposed to an excess of solid CaO, which reacts with CO2 as per to the equation CaO(s) + CO2(g) CaCO3(s) subsequent to the reaction was complete the pressure of the gas had dropped to 313torr. Explain how many moles of CO2 were in the original mixture? Presume no change in volume or temperature. Moles CO2
