Answer #1

gram molar mass of CCl4   = 12+35.5*4   = 154g/mole

mass of CCl4                     = 27.7g

no of moles of CCl4     = W/G.M.Wt

                                     = 27.7/154   = 0.18 moles of CCl4

1 mole of CCl4 contains 1 mole of C (carbon)

0.18 mole of CCl4 contains 0.18 mole of C ( carbon)
