The normality of 26% (wt/vol) solution of ammonia (density =0.855) is approximately:
The normality of 26% (wt/vol) solution of ammonia (density =0.855) is approximately:
Show Hint
For acids/bases:
Normality=Molarity× n
where n is basicity or acidity.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: 26% (w/v) means 26g of NH₃ per 100mL.
Step 2: Mass per litre: 260g/L
Step 3: Molar mass of NH₃=17. Molarity=(260)/(17)≈15.3M
Step 4: Ammonia is a monobasic base: Normality=Molarity=15.3
