Answer:

Explanation:

144 g of mg(co3)2 contain → 96 g of oxygen atom

1 g of mg(C03)2 contain → 96/144 g of oxygen atom

9 g of mg(CO3)2 contain → (96/144) × 9  g of oxygen atom

                                                =6 g of oxygen atom

∴ no.of moles of oxygen atom =given mass / GAM

                                                   = 6/16

                                                    =0.375 MOLES
