Answer to Question #48062 in Other Chemistry for Lizeth Falcon
if 45.5 mL of 3.0 M sodium chloride solution is diluted to a final volume of 500.0 mL, what is the molarity of the diluted sodium chloride solution?
First of all we findmoles of sodium chloride in first solution: n = 0.0455 L*3 = 0.14 moles An amount of sodiumchloride is the same in both solutions. So, then we can calculate a molarity in secondsolution: c = 0.14 moles/0.5 L = 0.28 M
