7 Give all answers to 3 significant figures. Ammonium nitrate decomposes on heating to give nitrogen (II) oxide and water as follows: NH4NO3(s) → N₂O(g) + 2H2O(l) (A, values: N = 14.0; H= 1.0; 0 = 16.0)
a) Deduce the formula mass of ammonium nitrate.
b) C How many moles of ammonium nitrate are present in 0.800 g of the solid?
c) Calculate the volume of N₂O gas that would be produced from this mass of ammoniu nitrate?​
