Interpretation:
Among the samples, A, B, C of coal, the one with the smallest mass percent of sulphur 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:
