Unformatted text preview: 1 mol = 4.97g / 0.01838mol = 270.4 g/mol molar mass of C 9 H 11 O = 135.2 g/mol n= 270.4 g/mol / 135.2g/mol n=2 The molecular formula for Estrone is C 18 H 22 O 2 15) Ammonia = NH 3 Ammonium nitrate = NH 4 NO 3 Molar mass = 17 g/mol Molar mass = 80.1 g/mol % of N = 14.01 g/mol / 17g/mol % of N = 28g/mol / 80.1g/mol % of N = 82.9 % of N = 35% The liquid ammonia (NH 3 ) would be better because it has a higher concentration of Nitrogen by mass. The ammonia has 82.9% Nitrogen compare to 35% Nitrogen of the ammonium nitrate....
