One volume of nitrogen reacts with 3 volumes of hydrogen to produce two volumes of ammonia gas. How much nitroget? and hydrogen gas is required to produce `400 cm^(3)` of ammonia gas ?

Explanation

To solve the problem of how much nitrogen and hydrogen gas is required to produce 400 cm³ of ammonia gas, we can follow these steps:

### Step 1: Write the balanced chemical equation
The balanced equation for the reaction of nitrogen and hydrogen to form ammonia is:
\[ N_2 + 3H_2 \rightarrow 2NH_3 \]

### Step 2: Identify the volume ratios
From the balanced equation, we can see the volume ratios:
