Calculate the percentage by mass of each element in H2S04?

Hey guys, I've been tying to work this out but no luck on this, can anyone help me with the step by step answer please? thanks in advance very much, will rate.Calculate the percentage by mass of each element in H2S04?
I'm doing this from memory without a calculator so you may want to double check on this.

H2=2g. S=32g. O4=64g

Total of 98g.

2/98*100 is the percentage of Hydrogen.

Repeat for the other two elements.
