Question

In which case the number of hydrogen atoms are more: 2 moles of HCl or 1 mole of H2SO4​

Answer 1

Answer:

both cases posses equal H

Explanation:

2 moles of HCl =2HCl here no of hydrogen is 2

1 mole of H2SO4, here also the no of hydrogen is 2. so both are equal

mark me if u liked it

Answer 2

Answer:

2 moles of HCl and 1 mole of H₂SO₄ contain an equal number of hydrogen atoms (12.044×10²³)

Explanation:

Given,

    moles of HCl = 2mol.

moles of H₂SO₄ = 1mol.

  1 mole of HCl ≡ 6.022×10²³ molecules of HCl

 2 mole of HCl ≡ 12.044×10²³ molecules of HCl

1 molecule of HCl contains 1 H atom.

Thus, 2 moles of HCl contains 12.044×10²³ H atoms.

 1 mole of H₂SO₄ ≡ 6.022×10²³ molecules of H₂SO₄

1 molecule of H₂SO₄ contains 2 H atoms.

6.022×10²³ molecules of H₂SO₄ contains 2×6.022×10²³ H atoms.

Thus, 1 mole of H₂SO₄ contains 12.044×10²³ H atoms.

The required answer is both contains the same number of hydrogen atoms
