Question

If you have 200 mL of a 2 M NaCl solution, how many mL of a 0.5 M NaCl solution can you make?

Answer 1

Answer:

800 ml of NaCl solution can be prepared

Explanation:

We use the formula for dilutions:

C1x V1 = C2xV2

(before dilution: C1 and V1)

(after dilution: C2 and V2)

200ml x 2M = 0,5 M  x V2

V2= (200ml x 2M)/0,5M=800ml
