Answer to Question #56057 in General Chemistry for sue
What is the molarity of a solution containing 12.4 g of KCl in 269 mL of KCl solution?
Express your answer with the appropriate units.
molarity = moles of solute / liters of solution
12.4 g of KCl in 269 mL of KCl
moles = grams / molar mass
12.4 g / 74.5 g/mol = 0.166 mol
molarity = 0.166 mol / 0.269 L = 0.6 M
