Answer to Question #165754 in Chemistry for Phyroe

Question

To dilute 150 ml of 1 F CaCl2 solution to 0.02 F would require how many milliliters of water?

Answer 1

C_M = n/V

n₁ = n₂

C_M1 x V₁ = C_M2 x V₂

1 x 0.150 = 0.02 x V₂

V₂ = (1 x 0.150)/0.02 = 7.5 L = 7 500 ml

The required amount of water is: 7 500 - 150 = 7 350 ml
