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
