Question

The no. Of hydrogen atoms in 0.25 mole of h2so4

Answer 1

Explanation:

1 mole of a compound contains number of atoms. By Stoichiometry of the compound: 1 mole of sulfuric acid has number of hydrogen atoms. So, 0.5 moles of sulfuric acid will contain number of hydrogen atoms

Thanks!❤

Answer 2

Heya!!

As we know, 1 mole of H2So4 has 2 moles of hydrogen atoms, 1 mole of sulphur atom and 4 moles of the oxygen atoms.

For 2 moles,

1 : 2 = 0.25 : x

therefore x = 0.50 moles

Now, one mole contains 6.02 X 1023 atoms

hence,

1 : 6.02 X 1023 = 0.5 : x

x = 3.011 X 1023 hydrogen atoms.

Thanks!
