Solution

Step 1: Given data:

We are given a peroxide anhydrous enzyme in which Se is present as = 0.5% by weight
This means we can say that 0.5gofSe is present in 100g of the enzyme.

The atmoic weight of Se is given as = 78.4gm

Step 2: Calculation of molecular weight of peroxidase anhydrous enzyme:
78.4gofSe will be present in,

=1000.5×78.4

=1.568×104gm of peroxidase anhydrous enzyme

Hence, the minimum molecular weight of peroxidase anhydrous enzyme is calculated as 1.568×104gm.
