x/6.022*10^23 = 2.2483*10^-19/793
x = 170.7347 g/mole

simplify the problem. If you have 10 bicycles and the bicycles weigh 200 pounds, how would you find the weight of a single bicycle? You'd divide 200 pounds by 10, to get the answer that 1 bicycle weighs 20 pounds. Do the exact same thing here.

2.2483x10^-19g / 793 = your answer
