The gram formula mass of KCl (potassium chloride) is calculated by adding the atomic masses of potassium (K) and chlorine (Cl) together. The atomic mass of potassium (K) is approximately 39.10 grams per mole (g/mol), and the atomic mass of chlorine (Cl) is approximately 35.45 g/mol. Therefore, the gram formula mass of KCl is approximately 39.10 g/mol + 35.45 g/mol = 74.55 g/mol.
