Interpretation:
The mass percent of the calcium in dolomite and the richer source of calcium among dolomite and fluorite is to be determined.
Concept introduction:
The mass fraction of an element in a compound is defined as the ratio of the sum of the masses of all the atoms of that element to that of the mass of one mole of compound.
Mass percent of an element represents the percentage concentration of that element in a compound. It is equal to the mass fraction expressed as a percentage. The general formula to calculate the mass percent of an element A in a compound is as follows:
