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

Options

  1. A1.5
  2. B0.4
  3. C15.3
  4. D4

Correct answer

C. 15.3

Step-by-step solution

Wt. of NH3=26g=2617geq=1.53geq\mathrm{NH}_{3}=26 \mathrm{ g}=\frac{26}{17} \mathrm{ g} \mathrm{eq}=1.53 \mathrm{ g} \mathrm{eq} Vol. of soln. =100mc=0.1L∴=100 \mathrm{mc}=0.1 \mathrm{ L}\therefore Normality =1.530.1=15.3N=\frac{1.53}{0.1}=15.3 \mathrm{ N}
