An aqueous solution of ammonium nitrite decomposes when heated to give off nitogen gas and water. This reaction can be used to prepare pure nitrogen gas. How many grams of ammonium nitrite must have reacted if 3.75 liters of nitrogen gas was colleced over water at 25˚C and 97.8 kPa? I keep getting 11.8 but its saying im wrong.whats the correct steps to solve it

If you will show your work I will find the error.
Steps?
1. Write and balance the equation.
2. Find pressure H2O @ 25C and calculate pressure dry N2.
3. Find mols N2
4. Use the equation to convert mols N2 to mols NH4NO3.
I just re-read the problem. Are you using NH4NO3 or NH4NO2?
