Chemistry questions and answers. What is the molar concentration of a 20.0% w/v (m/v) KCl solution? The information below may be helpful: Molar mass of KCl: 74.551 g/mol Density of water: 1.00 g/mL Enter your answer in standard notation with the correct number of significant figures. Molarity = M.
Some of the main characteristics of potassium chloride include: K and Cl combine to form the metal halide KCl which is an odorless salt. It is a white-colored compound that is highly water soluble. Potassium supply limits the growth of many plants, hence most of the potassium chloride manufactured is used to make fertilizer, known as potash.
