How to make a solution of a certain molarity?

Question

Let's say I have an unlimited supply of some pure product, such as Ascorbic Acid (C₆H₈O₆).

I will mix it with some deionized water. If I wanted make a specific solution of a certain molarity, would I simply divide moles/liters?

For example:

> If I have 9.98 grams of C₆H₈O₆ and convert that to moles (MM of AA is 176.12 g/mol) and get 0.0566 mol C₆H₈O₆

> Then I use about 230ml or 0.23L

> Then to get molarity = 0.0566mol/0.23L = 0.246 M

Would this be correct or am I going about this wrong? Thank you for any advice.

Answer 1

You are absolutely correct. The only correction I’d make is in your significant figures. Since 230 ml (0.23 L) has only 2 sig figs, your answer should have no more that. Answer would be 0.25 M
