A pharmaceutical oxide drug contains 24% oxygen .The minimum molar mass of the drug is..1)242)66.663)1804)103...plz explain
Hi,Let's say the mass of the compound is x. By mass, it contains 24 % oxygen. The atomic mass of oxygen is 16g.Let there be 100g compond in which there is 24 g oxygen.(To take the minimum mass, assume that there is 1 oxygen atom in it )But, actually it's 16 g not 24 g.So, using unitary method,If 24 g of oxygen = 100g of compound16g of oxygen = x gram of compound.Solving for x:X= 100*16/24 = 66.66Hence, the mass of compound is 66.66g.
