The percentage of Se in peroxidase anhydrous enzyme is 0.5% by weight (atomic mass = 78.4). Then minimum molecular mass of peroxidase anhydrous enzyme is 1.568 × 104 .

Explanation :-

0.5g Se = 100 gm peroxidase anhydrous enzyme 78.4g Se = 100/ 78.4  × 0.5 = 1.568 × 104 

 Minimum molecular mass ⎯→ molecule at least contain one selenium.
