Molarity question?

to what volume must 499 mL of 11 M Ca(OH)2 solution be diluted to make a 2 M Ca(OH)2 solution?

Please show how you got the answer

Answer:
You need to use this equation: C1V1=C2V2.
C1 is your initial concentration
V1 is your initial volume.
C2 is the concentration you want
V2 is your unknown.
(11M)*(0.499L)=(2M)(V2)
V2=2.74 L or 2744.5 mL
(M1)(V1) = (M2)(V2)

(11M)(499mL) = (2M)(XmL)
volume (in mL) = (11M*499mL)/2M
