The molar mass of I2 : 283.81 g/mol

Further explanation

Given

I2 compound

Required

The molar mass

Solution

Relative atomic mass (Ar) of element : the average atomic mass of its isotopes  

Relative molecular weight (M) : The sum of the relative atomic mass of Ar  

M AxBy = (x.Ar A + y. Ar B)  

So for I2 :

= 2 x Ar I

= 2 x 126.90447 g/mol

= 253. 809 g/mol

= 253.81 g/mol
