Question

The normality of $26\%$ (wt/vol) solution of ammonia (density $= 0.855$ ) is approximately :

• A. 1.5
• B. 0.4
• C. 15.3
• D. 4

Answer 1

Answer: (C)

15.3

Answer 2

Wt. of $NH _{3}=26\, g =\frac{26}{17} g ; eq =1 \cdot 53\, g\, eq$
Vol. of soln. $=100 \,mc =0.1\, L$
$\therefore$ Normality $=\frac{1.53}{0.1}=15.3 \,N$
