. What is the molar mass (to the nearest tenth of a gram/mole) of each of the following
KCl
To find the molar mass of KCl, we need to determine the atomic masses of potassium (K) and chlorine (Cl), and then calculate the total mass of one mole of KCl.
The atomic mass of potassium (K) is approximately 39.1 grams per mole (g/mol), while the atomic mass of chlorine (Cl) is approximately 35.5 g/mol.
To calculate the molar mass of KCl, we add the atomic masses of potassium and chlorine together:
Molar mass of KCl = Atomic mass of K + Atomic mass of Cl
= 39.1 g/mol + 35.5 g/mol
= 74.6 g/mol (to the nearest tenth)
Therefore, the molar mass of KCl is approximately 74.6 grams per mole.
