Question

calculate relative molecular mass of h2so4

Answer 1

what is 5 rational numbers

Answer 2

The molecular mass of hydrogen in H2SO4 = 2 a.m.u
The molecular mass of oxygen in H2SO4 = 16*4 = 48 a.m.u
The molecular mass of Sulphur = 32 a.m.u

The molecular mass of H2SO4 = 2 + 48 + 32 = 82 a.mu.

Hope this helps you.
