Question

Calculate the volume of ammonia gas produced at STP when 140 g of nitrogen gas reacts with 30 g of hydrogen gas. (Atomic mass =N=147u,H=1u)​

Answer 1

Answer:

(10 × 22.4 L = 224 L )

Explanation

.Simply, the reaction is  N 2 + 3 H 2 = 2 N H3

140 g    N 2  means  140 ÷28 = 5 mol;

30 g  H 2  means  30 ÷2 = 15 mol

From 1 mol of  N 2  2 mol  N H 3  is prepared in perfect presence of  H 2

Hence,  10 mol of  N H 3  will be produced.

We know,1mol of any ideal gas at STP ( 0 ∘ C  and  1 atm ) contains 22.4L of the ideal gas.

Produced ammonia is  224  L
