In order to determine the amount of a substance in 1 gram of calcium carbonate (CaCO3), it is necessary to find its molar mass.
The molar mass of calcium (Ca) is 40 grams / mol.
The molar mass of carbon (C) is 12 grams / mol.
The molar mass of oxygen (O) is 16 grams / mol.
The molar mass of calcium carbonate (CaCO3) is 40 + 12 + 16 x 3 = 100 grams / mol.
1 gram of calcium carbonate (CaCO3) contains 1 gram / 100 grams / mol = 0.01 mol of the substance.
