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?

Respuesta :

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
