Question

In which case the number of hydrogen atoms is more:2 moles of HCL or 1 mole of H2SO4

Answer 1

Answer:

As we know that

1 mol of hcl contains 1 hydrogen atom

So 2 mol contains 2 hydrogen atoms

Here in NH3

1 mol contains 3 hydrogen atoms

So In NH3 no of hydrogen atom is more

Answer 2

Answer:

same no of atoms

Explanation:

because In 1 mole of HCL there is 6.022*10^23 atoms. so in 2 moles there will be 2 * 6.022*10^23 = 12.044*10^23 no of atoms

and in H2SO4 mass = H2 which means it has two atoms of hydrogen.

so in H2 there will be same no. of atoms in above

so the no. of atoms is same in both cases
