Calculate the mass of the precipitate formed as a result of passing carbon dioxide through 370 g of calcium hydroxide solution with a mass fraction of 0.2%.

Ca (OH) 2 + CO2 = CaCO3 + H2O Mass of calcium hydroxide in solution 370 grams * 0.002 = 0.74 grams => the amount of the in-va is 0.74 grams ÷ 74 grams / mol = 0.01 mol = amount calcium carbonate substances => mass of calcium carbonate (sediment) = 0.01 mol * 100 g / mol = 1 g
