Expert Answer

Let the mass of compound  = 100 g

Mass of carbon = 40 g

Mass of carbon in the compound = (40 / 100 ) * 90

                                                               = 36 g

No . of carbon atoms = Given mass / molar mass of carbon atom

                                       = 36 / 12 = 3
