(a) 2NH4NO3 = 2N2O + 4H2O

(b) 20.24 grams

Explanation:

(a) 2 moles of ammonium nitrate decomposes to form to 2 moles of nitrous oxide and 4 moles of water.

(b) From the equation of reaction,

2 moles of NH4NO3 are used up to form 2 moles of N2O

0.46 mole of NH4NO3 would yield 0.46 mole of N2O

Mass of N2O formed = number of moles * MW = 0.46 * 44 = 20.24 grams
