Answer 2

Answer:

7.248x10²⁶atoms

Explanation:

Isopropanol C3H7OH=60g/mol

1 mole contains 3 moles of carbon & 1 mole of oxygen

∴60g of isopropanol contains 3 moles of carbon & 1 mole of oxygen

∴ In 72.5kg of isopropanol,

Moles of C=6072.5×103×3=3.625×103

                    =3.625×6×1023×103 atoms

                    =2.1×1027 atoms

Moles of O=6072.5×103×1

                    =1.208×103=1.208×6×10623×103

                    =7.248×1026 atoms
