Some Basic Concepts Of Chemistry Question 42

Question: A mixture of $N H_{4} N O_{3}$ and ${(N H_{4})}_{2} H P O_{4}$ contain 30.40% mass per cent of nitrogen. What is the mass ratio of the two components in the mixture?

Options:

A) 2 : 1

B) 1 : 2

C) 3 : 4

D) 4 : 1

Show Answer

Answer:

Correct Answer: A

Solution:

[a] Let w.t. of $N H_{4} N O_{3}$ and ${(N H_{4})}_{2} H P O_{4}$ are x and y gram respectively $\frac{\frac{x}{80} \times 2 \times 14 + \frac{y}{132} \times 2 \times 14}{x + y} \times 100 = 30.4$
$\Rightarrow x : y = 2 : 1$
