There are 18 atoms of H per molecule, from the formula

2.84 x 10^23 atoms of H x 1 molecule / 18 atoms of H = 1.58e22 molecule.

az_lender say: Each molecule of ibuprofen contains 18 atoms of hydrogen, so your problem becomes:
(2.84 x 10^23 H atoms) * [(1 ibuprofen molecule)/(18 H atoms)]
= about 1.5 x 10^22 ibuprofen molecules, but use a calculator.
