what is the normality of a solution of ammonia, whose density is 0.885. it has 23% ammonia by weight -

1) 1.35 2)12.0 3) 19.1 4) 26.0

ans- 12.0 pls ans urgently

To find :
Normality of solution i.e water + ammonia form NH₄OH solution = ?

Formula used :
Density of NH₄OH  = M/V

Given :
Volume = 1L
Density= 0.885
Mass of NH₄OH = 1 x 0.885 = 0.885 g

Amount of  NH₃ = [(23/100) x0.885] = 20.335/100 = 0.20
Normality normality of a solution of ammonia = [(Amount of NH₃ in NH₄OH/Equivalent Molar mass of NH₃) x volume]
 => (0.20/17)x1000 =200/17 = 11.7 = 12 N
