Question

Insulin contains 3.4% sulphur. Calculate the minimum molecular mass of insulin.

Solution

Correct option is

941.2amu

 

Minimum molecular mass of insulin will be the mass containing at least one atom of sulphur.

One atom of S = 32amu.

Now, 3.4amu of sulphur is present in 100a.m.u of insulin.

   

                                                                   = 941.2amu

Hence, minimum molecular mass of insulin = 941.2amu
