Vedclass · Answer

(D) The minimum molecular weight of a compound is calculated by assuming that it contains at least one atom of the element in question.The atomic weight of sulphur $(S)$ is $32 \ u$.Given that insulin contains $3.4\%$ sulphur by mass,this means $3.4 \ g$ of sulphur is present in $100 \ g$ of insulin.To find the minimum molecular weight,we assume $32 \ g$ of sulphur is present in the molecule:$	ext{Minimum molecular weight} = \frac{100 	imes 32}{3.4} \approx 941.17 \ g/mol$.Rounding to the nearest provided option,the value is $940$.

Insulin contains $3.4\%$ sulphur. The minimum molecular weight of insulin is
