Question

Hydrogen atoms in 0.1 mole of h2so4

Answer 1

1 mole of H2S04 has 2×6.022×10²³ H atoms
then .1 mole has 12.044× 10²²H atoms..

Answer 2

The hydrogen atoms in $H_2SO_4$ is $1.2044 \times 10^{23}$

Explanation:

Number of hydrogen atoms present in 1 mole of $H_2SO_4$ are $2 \times 6.022 \times 10^{23}$, i.e., $12.044 \times 10^{23}$

Since, one mole of $H_2SO_4$ contains 2 times of Avogadro number of hydrogen atoms thus, by using unitary method 0.1 mole contains 0.1 x Avogadro number of atoms of Hydrogen.

Here is the calculation.

The chemical reaction for the formation of $H_2SO_4$ is:

$H_2O + SO_3 \rightarrow H_2SO_4$

Therefore, 1 mole of $H_2$ = $1 \times 12.044 \times 10^{23}= 12.044 \times 10^{23}$

Thus, 0.1 mole of $H_2$ = $0.1 \times 12.044 \times 10^{23} = 1.2044 \times 10^{23}$
