Question

Calculate the no. Of oxygen atoms in 0.5 mole h2so4

Answer 1

Answer:

4 atoms of oxygen are present in 0.5 mole in sulfuric acid H2SO4

Answer 2

Given: 0.5 moles of sulfuric acid.

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

Solution:

The number of oxygen atoms can be determined as follows-

The chemical formula of sulfuric acid is $H_2SO_4$.

One mole of the sulfuric acid molecule has four oxygen atoms.

Thus we can write-

1 mole of sulfuric acid contains $6.023×10^{23}×4=24.092×10^{23}$ number of oxygen atoms.

0.5 mole of sulfuric acid contains $24.092×10^{23}×0.5=12.046×10^{23}$ number of oxygen atoms.

Thus 0.5 mole of sulfuric acid contains $12.046×10^{23}$ number of oxygen atoms.
