Question

A compound contains 0.5 mol Na, 0.5 mol N, and 10 mol H. The empirical formula of the

compound is -

Answer 1

NaNH₂₀

Step-by-step explanation:

0.5 mol Na, 0.5 mol N, and 10 mol H

To obtain the empirical formulae, we find the mole ratio between the elements and this is done by dividing all through by the smallest mol (0.5)

Na = 0.5 / 0.5 = 1

N = 0.5 / 0.5 = 1

H = 10 / 0.5 = 20

The mole ratio is used to write the empirical formulae. It is given as;

NaNH₂₀
