How many liters of nitrogen gas is produced if 50.0L of water is produced at STP?

Explanation:

1. Chemical equation

Ammonium nitrite is a solid compound that decomposes into nitrogen gas and water vapor as per this chemical equation:

2. Mole ratio

3. Volume ratio

Since, both species are gases and are at same temperature and pressure, the volume ratio is equal to the mol ratio.

Thus, the volume ratio is:

4. Use the volume ratio with the known amount of water produced

i believe it is 40–40–20%

explanation:

it is the most commonly accepted one
