Calculate the % composition by mass of oxygen present in H2SO4.
A
16.3%
B
65.25%
C
32.6%
D
57.14%
Explanation: 

Detailed explanation-1: -Hence, 64 g/mol oxygen is present in 98 g/mol of the sulphuric acid. Take the ratio of mass of oxygen to the total mass of sulphuric acid multiplied by 100 to calculate in terms of percentage. ⇒ The percentage of oxygen in the sulphuric acid is 65.30% .

Detailed explanation-2: -Thus, the percentage composition of oxygen, hydrogen, sulphur and oxygen in Sulphuric acid H 2 SO 4 is 2 . 04 %, 32 . 65 % and 65 . 3 % respectively.

Detailed explanation-3: -1 Answer. This amount of H2SO4 would contain 10.2 moles of oxygen which is 163.1 grams.

Detailed explanation-4: -Sulfuric Acid, H2SO4 is a chemical compound made up of two hydrogen atom, one sulfer atom, and four oxygen atoms.

Detailed explanation-5: -Therefore % of S in H2SO4=9832×100=32. 65%.
