For finding the molecular mass , you need to calculate the sum of masses of different elements multiplies by their number of atoms in one molecule of its compound.

#=> 2xx"Mass of hydrogen" + "Mass of sulphur" + 4xx"Mass of oxygen"#

Here , Mass of one hydrogen atom #=1u#.

Mass of one sulphur atom #=32u#.

Mass of one oxygen atom #=16u#.

We get , Mass of one molecule of #H_2SO_4#

#=> 2xx1 + 32 + 4xx16#

#=> 2 + 32 + 64#

#=> 98u#
