Heya !!
Let's say the mass of the compound is x.
By mass, it contains 3.2 % oxygen.
The atomic mass of oxygen is 16g.
Let there be 100g compond in which thereis 3.2 g oxygen.(To take the minimum mass, assume that there is 1 oxygen atom in it )But, actually it's 16 g not 3.2 g.
So, using unitary method,If 3.2 g of oxygen = 100g of compound 16g of oxygen = x gram of compound.
Solving for x:X= 100*16/3.2 = 500
Ans.---> 500
Hope it helps ☺
