Calculate each of the following:(a) Mass % of I in

Solution 18P:

Here, we have to calculate the mass percent of each atom in the molecules.

We can calculate the mass % from the following equation

Mass percent of element X = 100%

Step 1:

(a) Mass % of I in

Here, we are going to calculate the mass % of I in

The molar mass of = 469.4 g/mol

Since,

1.0 mole of  = 2.0 moles of I

The molar mass of I =126.9 g/mol

Therefore, the mass of I in  = 2.0 moles of I

                                        = 253.8 g of I

Therefore,

Mass percent of element I = 100%

                                     = 100%

     = 54.0690

     = 54.07% of I

Thus,  54.07 % of I is in
