Some Basic Concepts Of Chemistry Question 61

Question: 50mL $ 10NH _2SO _4 $ , 25mL $ 12NHCl $ and 40ML 5N $ HNO _3 $ were mixed together and the volume of the mixture was made 1000 mL by adding water. The normality of the resultant solution will be

Options:

A) 2N

B) 1N

C) 3N

D) 4N

Show Answer

Answer:

Correct Answer: B

Solution:

[b] $ N=\frac{N _1V _2+N _2V _2+N _3V _3}{Totalvolume} $ $ =\frac{50\times 10+25\times 12+40\times 5}{1000}=1N $
