What volume of nitrogen gas is produced when 103 liters of nitrogen monoxide react? ( all gassed are at stp)

51.5 L

Explanation:

1. Write the chemical equation.

You don’t give the reaction. However, if all the N₂ comes from NO, we can write a partial equation. The important point is that we must balance the N atoms.

      2NO + … ⟶ N₂ + …

V/L:  2 L              1 L

2. Calculate the volume of N₂.

We can use Gay-Lussac's Law of Combining Volumes to solve this problem.

According to the law, 2 L of NO produce 1 L of N₂.

Then, the conversion factor is
