Question

Calculate the percent nitrogen in NH4NO3.Group of answer choices17.5%8%60%28%35%

Answer 1

In order to find the percent composition for Nitrogen in NH4NO3, we will need to work with all the masses from this compound, so let's list them below:

NH4NO3 = 80.04 g/mol

N = 14 grams, but we have 2 nitrogens, therefore = 28 grams

H = 1 gram, 4 Hydrogens = 4 grams

O = 16 grams, 3 Oxygens = 48 grams

Now we take the total mass of the compound as 100% and check how much it will be made by Nitrogen:

80.04 g = 100%

28 g = x %

x = 34.98%, which we can round up to 35% therefore the answer will be letter E
