    1 mole of atoms = Gram atomic mass

    So, 1 mole of Ca atoms=Gram atomic mass of Ca

                                          =40g

    Now,  40 g of calcium = 1 mole of calcium

    So,      8 g of calcium =1/40×5 mole

                                        =1/5 mole

                                        =0.2 mole

    Thus,there are 0.2 mole in 8 g of calcium.
