Calculate the mass of the obtained salt, if 15 grams of calcium oxide and 5 liters of carbon dioxide were taken

Calculate the mass of the obtained salt, if 15 grams of calcium oxide and 5 liters of carbon dioxide were taken to obtain it, and its yield is 80% of the theoretically possible.

CaO + CO2 = CaCO3
1) v (CaO) = m / M = 15/56 = 0.27 (mol)
2) v (CO2) = V / Vm = 5 / 22.4 = 0.22 (mol) – lack
3) v (CaCO3) = v (CO2) = 0.22 (mol)
4) mt (CaCO3) = M * v = 88 * 0.22 = 19.36 (g)
5) mp (CaCO3) = mt * output = 19.36 * 0.8 = 15.488 (g)
Answer: m (CaCO3) = 15.488 (g)
