Explanation:
Detailed explanation-1: -Introduction. Potassium chloride (KCl) is a metal halide salt composed of potassium and chloride.
Detailed explanation-2: -Let us calculate the formula unit mass of $KCl$. We know that it contains one atom of potassium and one atom of chlorine in the chemical formula. Hence the formula unit mass of potassium chloride is $74.5$amu.
Detailed explanation-3: -The crystals of potassium chloride are made up of face-centred cubic (FCC) unit cells. The molar mass of KCl is 74.5513 grams/mol. Its density in the solid, crystalline form is 1.984 grams per cubic centimetre. The melting and boiling points of potassium chloride are 1040 K and 1690 K respectively.
