Solution calculation question?

Steelers72

You have a stock of 3M NaCl. You want to make a 1M solution. You should mix ___ ml of water with ___ ml of the stock to get the final concentration.

Is this a C1V1=C2V2 type of problem?

molar weight of NaCl is 58.4g/mol not sure if this affects the problem any?

I appreciate any help/guidance.

Yes, this is a C1V1 = C2V2 problem, except the question didn't specify how many of the 1M solution was required...

For every 100ml of 3M you need to add 200 ml of water to give 1M
3*100 = 1* Vml V=300ml
