Calculate the molarity of a solution prepared by dissolving 0.400 mol of KNO3 into enough water to make 350. mL of solution.

Answer 1

To calculate the molarity of the solution, first convert the volume of the solution from milliliters to liters:

350 mL = 0.350 L

Next, use the formula for molarity:

Molarity = moles of solute / liters of solution

Molarity = 0.400 mol / 0.350 L
Molarity = 1.14 M

Therefore, the molarity of the solution is 1.14 M.
