Solid sodium carbonate, Na2CO3, reacts with sulfuric acid, H2SO4, to produce CO2 gas according to the following equation: Na2CO3(s) + H2SO4(aq) →CO2(g) + H2O(l) + Na2SO4(aq) During an experiment to produce carbon dioxide gas, a student recorded the following data: P CO2 = 708.1 mm Hg V CO2 = 29.65 mL T CO2= 25.5 °C How many moles of CO2 were produced?

We can simply calculate for the number of moles CO2 produced by assuming that the gas is an ideal gas. Therefore, can be described by the equation:

PV = nRT

where P is pressure, V is volume, T is temperature, n is the number of moles and R is a gas constant.

PV = nRT
(708.1/760)(.02965) = n(0.08205)(25.5+273.15)
n = 0.00113 mol CO2 produced
