Question: An aqueous solution of ammonium nitrite, NH4NO2, decomposes when heated to give off nitrogen, N2. NH4NO2(s) 2H2O(g) + N2(g) This reaction may be used

An aqueous solution of ammonium nitrite, NH4NO2, decomposes when heated to give off nitrogen, N2.
NH4NO2(s) → 2H2O(g) + N2(g)
This reaction may be used to prepare pure nitrogen. How many grams of ammonium nitrite must have reacted if 3.75 dm3 of nitrogen gas was collected over water at 26C and 97.8 kPa?
