Problem- What mass (in grams) of NaCl would you need to add to 100.00 mL of solution to make a final concentration of 100.00mM NaCl?
I'm assuming that the solution is a solution of water? I'm not sure how you are supposed to tell from this question
Please perform what you can and illustrate your work so I can follow. Thanks
