A 0.360 M solution of KNO₃ (formula mass = 101.09) which contains 125 grams of solute would have a volume of ________.

Question

Quizplus · Accepted Answer

The correct answer is A because:Molarity = moles of solute / liters of solutionMoles of solute = mass of solute / molar mass of soluteMass of solute = 125 gMolar mass of solute = 101.09 g/molMoles of solute = 125 g / 101.09 g/mol = 1.236 molMolarity = 1.236 mol / 0.360 L = 3.43 MVolume of solution = moles of solute / molarityVolume of solution = 1.236 mol / 0.360 M = 3.43 L = 3430 mL
