Answer:
As we can see from the chemical formula given above, Sulphuric acid has 2 atoms of hydrogen, 1 atom of Sulphur and 4 atoms of oxygen. Therefore, to calculate molecular mass, we need to add the individual weights, i.e. The molar mass of any element or compound is expressed in g/mol. Therefore, the answer is 98.08 g/mol.
