What is the concentration of a 450 mL solution that contains 1.58 moles of iron (II) chloride?

Answer 1

Molar concentration or molarity (M) is defined as moles of solute per liter of solution.

moles of FeCl2 = 1.50 moles

liters of solution = 450 ml x 1 L/1000 ml = 0.450 L

Molarity = 1.50 moles/0.450 L = 3.33 M iron (II) chloride
