The chemical formula for sulfuric acid is H2SO4. In 2H2SO4, the number of hydrogen atoms is, the number of sulfur atoms is, and the number of oxygen atoms is.

Hydrogen = 4, Sulfur = 2 and Oxygen = 8

Explanation:

The 2 in front of the chemical formula for H2SO4 indicates that there are 2 molecules of sulfuric acids.

Thus the number of atoms of hydrogen, sulfur and oxygen in 2H2SO4 is given below as;

No of hydrogen atoms = 2 x 2 = 4

No of sulfur atoms = 2 x 1 = 2

No of oxygen atoms = 2 x 4 = 8
