Answer 2

Given: 9.8 grams of sulfuric acid.

To find: We have to find the number of atoms.

Solution:

The chemical formula of sulfuric acid is $H_2SO_4$.

The atomic weight of H is 1, sulfur is 32 and oxygen is 16 grams.

Thus, the molecular weight of sulfuric acid is 1×2+32+16×4=98 grams.

Sulfuric acid contains a total of 7 atoms.

98 grams of sulfuric acid contains $7×6.023×10^{23}$ number of atoms.

9.8 grams of sulfuric acid contains $7×6.023×10^{23}×9.8/98=42.161×10^{22}$ number of atoms.

9.8 grams of sulfuric acid contains $42.161×10^{22}$ number of atoms.
