An unknown compound has the following chemical formula: zn(cn)x where x stands for a whole number. measurements also show that a certain sample of the unknown compound contains 9.7 mol of nitrogen and 4.9 mol of zinc. write the complete chemical formula for the unknown compound.

Explanation:

According to the law of definite proportions, particles in a compound combine by a defined stoichiometric ratio. This ratio is also calculated in terms of moles.

In order to find the ratio between the particles in a compound, we need to find the molar ratio of each species.

Notice that the ratio between the number of moles of zinc to the number of moles of nitrogen is:

This means if we are given 1 zinc ion, we expect to have a total of 2 nitrogen atoms. Therefore, x = 2.
