Can someone tell me if this is right please?

 

Theoretical yield of H2SO4:

Relative atomic masses: H = 1; S = 32; O = 16; N = 14

Molecular mass of sulphuric acid H2SO4 = (1 x 1) + 32 + (16 x 4) = 97

Molecular mass of ammonia solution NH3 = 14 + (1 x 3) = 15

For sulfuric acid, note that you have 2 hydrogen molecules, not just 1.

 

For the ammonia, your addition is incorret (14 + 3 does not equal 15).
