hi there!
here is your answer!
Go to periodic table and determine the atomic mass average (atomic weight) of each element. Multiply each atomic mass by the number of atoms in the formula. Add up the results of step three: 2.015+32.066+63.998 = 98.079 = molar mass of sulfuric acid.
hope it helps!

The molar mass of a substance is numerically equal to the atomic mass or the molecular mass of the substance in ‘u’ and is the mass of one mole of the substance. It is measured in grams.
Now the molecular mass of a molecule is the sum of atomic masses of the elements present in a molecule. It is obtained by multiplying the atomic masses of each element by the number of its atoms present in the molecule and adding them together.
CO2 contains 1 atom of Carbon and 2 atoms of oxygen.
Therefore its molecular mass will be = 1 X (atomic mass of C) + 2 X (atomic mass of O )
= 1 X (12.011u) + 2 X (16.00 u) = 44.011 u.
Therefore, the molar mass will be numerically equal to molecular mass in grams and so will be 44.011 g per mol.
In case of atoms, the molar mass will be the atomic mass of elements expressed in grams. For example the atomic mass of oxygen atom is 16u, so the molar mass of oxygen atom will be 16g.
