calcium carbontate is burnt strongly to form calcium oxide +carbon dioxide gas what mass of calcium carbonate should be burnt to form 4.4g of carbon dioside gas pls ans now
The molar mass of carbon dioxide is 44 g/mol. Therefore, 4.4 g of carbon dioxide is equal to 0.1 moles of carbon dioxide. According to the balanced chemical equation, 1 mole of calcium carbonate produces 1 mole of carbon dioxide. Thus, to produce 0.1 moles of carbon dioxide, you need to burn 0.1 moles of calcium carbonate. The molar mass of calcium carbonate is 100.1 g/mol. Therefore, the mass of calcium carbonate needed to produce 4.4 g of carbon dioxide is (0.1 mol / 1) x (100.1 g / mol) = 10.01 g.
