Answer:

A sample of salt has 1.74 moles of sodium chloride. how many formula units of the ionic compound are in the sample?

Explanation:

Given, 1.74 moles of NaCl.

Since one mole of NaCl consists of --- [tex]6.023 * 10^2^3[/tex] formula units.

Then, 1.74mol of NaCl contains how many formula units of NaCl?

[tex]1.74 mol x \frac{6.023x10^2^3}{1 mol} \\=10.5x10^2^3[/tex]formula units.

Hence, the given sample has 10.5x10^23 formula units.
