Answer :
The mass of the iodine solid that participates is 5.076 g
The molecular formula of iodine is I₂.
To calculate the Molecular weight:
First, count the number of atoms of each element, and then multiply that number by the element's atomic weight.
The atomic mass of iodine is 126. 9⋅g⋅mol−1
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
