Question 2

How many grams of CO2 would be required to be passed through a tank of lime water to produce 100 grams of CaCO3? (Ca = 40, C = 12, 0 = 16)

Answer

Balanced Chemical Equation

CO2 + CaO = CaCO3

The molecular weight of CO2 = 12 + 16 × 2 = 44

The molecular weight of CaCO3 = 40 + 12 + 3 × 16 = 100 g

From the above-balanced chemical equation, it is clear that 44 g of CO2 is required to produce 100 grams of CaCO3.
