Insulin contains `3.4%` sulphur. Calculate minimum mol.wt. of insulin.

Text Solution

Verified by Experts

Minimum molecular mass of insulin will be the mass containing at least one atom of sulphur.
But one atoms of S = 32 amu
Given that 3.4 amu of sulphur is present in 100 amu of insulin
`therefore" 32 amu of sulphur will be present in insulin"=(100)/(3.4)xx32=941.2amu`
Hence, minimum mass of insulin = 941.2 amu.
