Answer 2

Answer:

Explanation:

6.022x10^23 molecules of iodine = 1 mol of iodine

1 molecules of iodine = 1 / 6.022x10^23

15 × 10^23 molecules of iodine  = 1 / 6.022x10^23 X 15 × 10^23

                                                    = 2.5 mole of iodine

2.5 mole = given mass/127

2.5 X 127 = given mass

given mass = 317.5
