Dear sankar.goswami@siemens.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
 
However answer to your first query is,
 
Molecular mass of sulphuric acid; H2SO4 = 98 u
One molecule of sulphuric acid H2SO4 contains 2 Hydrogen atoms + 1 Sulphur atom + 4 Oxygen atoms
According to the formula, we get,
