1 mole ammonia contains 3 moles of hydrogen atoms.

So 10 moles of ammonia will contain 30 moles of hydrogen atoms .

1 mole of sulphuric acid contains 2 moles of hydrogen atoms .

So 5 moles of sulphuric acid will contain 10 moles atoms.

Total number of moles of hydrogen atoms = 30+10 = 40 moles

2 moles of hydrogen atoms make 1 mole of hydrogen gas

So 40 moles of hydrogen atoms will make 20 moles of hydrogen gas.

1 mole hydrogen gas contains 6.023*10^23 molecules.

20 moles of hydrogen gas will contain 20×6.023×10^23 molecules

=120.46×10^23 molecules.

One molecule of given compound contains 11 atoms of oxygen.

Therefore, 3 moles of the compound contains 33 moles atoms of oxygen.

Therefore, 11 moles of ozone can be formed.

Therefore, no. of ozone molecules formed = 11×Avogadro's number = 11×6.023 × 10^23
