Quizplus · Accepted Answer

The molar mass of carbonic acid (H2CO3) is 62.01 g/mol, and the molar mass of carbon dioxide (CO2) is 44.01 g/mol. Therefore, 6.20 g of carbonic acid is equal to 6.20 g / 62.01 g/mol = 0.1 mol of carbonic acid. According to the balanced chemical equation, 1 mol of carbonic acid produces 1 mol of carbon dioxide. Therefore, 0.1 mol of carbonic acid will produce 0.1 mol of carbon dioxide, which is equal to 0.1 mol * 44.01 g/mol = 4.40 g of carbon dioxide.
