Question

Ammonia is a compound consisting of a 1:3 ratio of nitrogen and hydrogen atoms. If a sample contains 1983 hydrogen

atoms, how many total atoms are present?

Answer 1

2644 atoms

Explanation:

1983/3 = 661

1983 + 661 = 2644 atoms

Answer 2

2644 total N and H atoms

Explanation:

N/H is 1/3

N/H = 1/3

N/(1983) = 1/3

N = (1983/3)

N = 661 N atoms

1983 + 661 = 2644 total N and H atoms.
