Percentage of Se (atomic mass = 78.4) in peroxidase anhydrase enzyme is 0.5% by mass, then minimum molecular mass of peroxidase anhydrase enzyme is:

The enzyme must contain at least one atom of Se∵ 0.5 g of ‘Se’ is present in 100g of enzyme,∴  78.4 g of 'Se' is present in  ---(g) of enzyme,   molar mass = 100 × 78.40.5  = 1.576 ×  104 g
