What is the equivalent concentration in M/L of a 0.85% (W/V) NaCl (FW 58) solution?

Question

express (W/V) measurement in g/dL

I think I'm doing this wrong.

I have it set up like this so far:

85g/dL x 10 dL/1L x 1M/58 g and now I'm not sure where to go from here...am I doing this right?

thanks biochem...yeah, I had a typo. I have .85 written down. I did get .14something, close to .15
Thanks!

Answer 1

The main error you have is that 0.85% is 0.85 g/dl. Everything else is OK except that it is 1 mol/58g. If you correct the initial concentration statement, you'll end up with 0.146 mol/L. It should be close to 0.15 M
