Answer:
The answer is 5.076 g of iodine solid.
Explanation:
The molecular formula of iodine is I₂.
Molecular weight of I₂= molecular mass of I x 2 = 126.904 /mol x 2= 253.808 g/mol
Thus, to calculate the mass of I₂ there is in a mol, we have to multiply the amount of mol of I₂ by its molecular weight as follows:
0.0200 mol I₂ x 253.808 g/mol I₂ = 5.07616 g
The mass rounded to 3 significant digits is 5.076 g
