The chemical equation below shows the decomposition of ammonium nitrate (nh4no3)nh4no3 n20 2h20a chemist who is performing this reaction starts with 160.1 g of nh4no3. the molar mass of nh4no3 is 80.03 g/mol; the molarmass of water (h20) is 18.01 g/mol. what mass, in grams, of h20 is produced? o 9.01o 18.01o 36.03o 72.06

The answer is 72.06. The relative formula mass of N2O is 44 (14 + 14 + 16). The relative formula mass of 2H2O is 36 (2(1 + 1 + 16)). The total relative formula mass of the products is 44 + 36 = 80. The ratio of the relative mass of the products to the original mass of the reactants is 2:1. As the relative mass of water produced is 36, doubling this (to make the ratio) gives 72.06.

Hydrogen atoms can each form one covalent bond, while nitrogen atoms can each form three covalent bonds. Three pairs of electrons are shared in an ammonia molecule
