Vedclass · Answer

(A) The minimum molecular weight is calculated by assuming at least one atom of sulfur is present in one molecule of insulin.Atomic weight of sulfur $(S)$ = $32 \ g/mol$.Given that $3.4 \ g$ of sulfur is present in $100 \ g$ of insulin.Therefore,$32 \ g$ of sulfur will be present in $\frac{100}{3.4} 	imes 32 \ g$ of insulin.Minimum molecular weight = $\frac{3200}{3.4} = 941.176 \ g/mol$.

Insulin contains $3.4\%$ sulfur. What is the minimum molecular weight of insulin?
