To calculate the relative molecular weight of any substance, it is necessary to sum up the relative atomic masses of all the elements that make up this substance. The relative atomic masses of elements are found using the periodic system of D.I.Mendeleev. Relative molecular weight is a dimensionless quantity.
Mr (H2SO4) = Ar (H) * N (H) + Ar (S) * N (S) + Ar (O) * N (O) = 1 * 2 + 32 * 1 + 16 * 4 = 98.
