Question

52. If an enzyme contains 0.2% of magnesium by
mass, then the minimum molecular weight of the
enzyme is
(1) 16000
(2) 8000
(3) 200
(4) 12000​

Answer 1

Answer:

if we r talking about min mol weight then the enzyme must have one atom of magnesium.

so now

0.2= 1(atom of mg) × 24(mol wt of mg) ×100 /min mol wt of enzyme

0.2= 24 ×100 / M

M = 24×100/0.2

M = 12000

formula used : percentage composition of element= 1 × atomic weight of element × 100 / min mol wt of compound
