Calculate the molar mass of KCI 72 74.55g/mol 39.10 35.45

To calculate the molar mass of KCl (potassium chloride), we need to add the atomic masses of potassium (K) and chlorine (Cl).<br /><br />The atomic mass of potassium (K) is approximately 39.10 g/mol, and the atomic mass of chlorine (Cl) is approximately 35.45 g/mol.<br /><br />So, the molar mass of KCl is:<br /><br />Molar mass of KCl = Atomic mass of K + Atomic mass of Cl<br />Molar mass of KCl = 39.10 g/mol + 35.45 g/mol<br />Molar mass of KCl = 74.55 g/mol<br /><br />Therefore, the molar mass of KCl is 74.55 g/mol.
