Answer #1

1 mole of KNO3 ------------> 6.023 * 10^23 formula units of KNO3

6.023 * 10^23 formula units of KNO3 ---------> 1 mole of KNO3

7.47 * 10^24 formula units of KNO3 ---------> (7.47 * 10 ^ 24) / (6.023 * 10^23) mole of KNO3

                                                                   = 12.4025 moles of KNO3
