Question

Calculate the number of atoms present in 0.1 mole of H2so4

Answer 1

Answer:

in 1 molecule of H2SO4 there are 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms so there are total 1+2+4=7 atoms

Answer 2

Answer:

The number of atoms in 0.1 mole of sulphuric acid (H₂SO₄) is equal to 42.16 × 10²².

Explanation:

Given, The number of moles of Sulphuric acid = 0.1 moles

Atoms in one molecule of the Sulphuric acid = 7 atom

We know that one mole of any compound contains number of molecules equal to Avogadro number or 6.023 × 10²³ .

One mole of sulphuric acid has molecules = 6.023 × 10²³

0.1 mole of sulphuric acid has molecules $= 0.1\times 6.023\times 10^{23}$

                                                                   $= 6.023 \times 10^{22}$ molecules

The number of atoms in 6.023 × 10²² molecules of H₂SO₄ will be:

$= 6.023\times 10^{22}\times 7$

$= 42.16\times 10^{22}$ atoms

Therefore, the number of atoms in 0.1 mole of sulphuric acid (H₂SO₄) is equal to 42.16 × 10²².
