How many atoms of carbon are in 0.425 g of ibuprofen?

Explanation:

It is known that the chemical formula of Ibuprofen is .

According to Avogadro, 1 mole of an atom contains atoms.

As molar mass of Ibuprofen is 206.29 g/mol. So, number of moles of ibuprofen will be calculated as follows.

            No. of moles =

                                  =

                                  = mol

Since. there are 13 atoms of carbon present in a molecule of ibuprofen. Hence, total atoms of carbon present in mol of Ibuprofen will be as follows.

         = atoms

Thus, we can conclude that there are atoms of carbon are in 0.425 g of ibuprofen.
