Ammonia is a gas with a characteristic pungent odor. it is sold as a water solution used in household cleaning. the gas is a compound of nitrogen and hydrogen in the atomic ratio 1: 3. a sample of ammonia contains 7.933 g n and 1.712 g h. what is the atomic mass of n relative to h?

Atomic mass of N relative to H is 13.9.

In periodic table mass of N is around 14 RAM

Explanation:

1 mol of ammonia has 1 mol of N, and 3 mole of H

NH₃

1 mol of H weighs 1 g, so the mole of H, present in ammonia are:

1.712 g / 1 g/m = 1.712 mole

Since the ratio is 1:3

1.712 mole/3 = 0.57 mole of N are present in the amonia

To calculate the atomic mass of N relative to H, let's consider it as molar weight.

Molar weight = mass / mole

7.933 g / 0.57 mole = 13.9 g/m
