chemistry question (simple) or math. Please explain it. Please I really do not get it?

Question

have 5M NAOH
10% Sds
Want to make .2M NaOH
1%SDS
And 5ml of it.
How to do this?

Answer 1

Use C1xV1 = C2xV2 for both solutions. Add both volumes and then BTV (bring to volume with water).

Remember that C stands for concentration, V for volume and your final volume (V2) for both is 5mL.

Hope this helps!
