Q1:

Nitrogen content in ammonium sulphate (a fertiliser) is around __________ percent.

A 5

B 20

C 50

D 65

ANS:B - 20

The nitrogen content in ammonium sulfate (NH4)2SO4 fertilizer is approximately 20%. Ammonium sulfate is a common nitrogen fertilizer containing two ammonium ions (NH4⁺) and one sulfate ion (SO4²⁻). The nitrogen in ammonium sulfate is in the form of ammonium ions, and it contributes approximately 20% nitrogen by weight. So, the correct option is: 20
