Example: A compound contains 8% sulphur by mass. The minimum molecular weight of the compound is: Like in this question least molecular mass is asked . There you know that 8% sulphur is present, so you'll use the formula Molecular mass of element / total molecular mass of compound * 100 = percentage of element
