Calculate the molar mass of potassium chloride, KCI . \begin{tabular}{l}6.74 g \\ 67.4 g \\ Submit \\ Request Answer \\ 54.6 g \\ \\ \hline\end{tabular}

To find the molar mass of potassium chloride (KCl), we start by looking at the atomic masses of its components. Potassium (K) has an atomic mass of approximately 39.1 g/mol and chlorine (Cl) has an atomic mass of about 35.5 g/mol. By adding these together, we get: Molar mass of KCl = 39.1 g/mol (K) + 35.5 g/mol (Cl) = 74.6 g/mol. So, the molar mass of potassium chloride is approximately 74.6 g/mol. For those engaging in calculations like this, always double-check your periodic table for the most accurate atomic masses since they can vary slightly based on the source! Also, remember that a common mistake is to confuse KCl (potassium chloride) with KClO3 (potassium chlorate) which would have a different molar mass due to the additional oxygen.
