How many grams of NaCl are needed to make a 2M stock solution?

[liam91]

Homework Statement

- How many grams of NaCl (molecular weight = 58 Da) would you have to dissolve in 50ml to make a 2M stock solution?

The Attempt at a Solution

I have thought about simply multiplying 58 by 0.1 = 5.8 g, but am not sure if this is correct.

It's just the daltons that are throwing me a bit off, also I wasn't too sure if i should be implementing n = m/M.

Thanks everyone.

Where did you got 0.1 from? (Note: I am not saying it is wrong, I am just asking where it came from).
