Hey all.

I'm new here, and I have become pretty interested in chemistry, so I want to be good at it...this
means understanding the same thing over and over for me.

So, 1 mol/L means that you have 1 mol in one liter of a solution. 0,1 mol/L must be 100 mL, right?

But, I just remember seeing this as 0,1 M at some point....is that a 'legal' way to write it? 0,1 M
instead of 0,1 mol/L

That's all for now...

Thanks!!

Molar concentration (M) is always referred to moles in 1L.
in 100 mL od 1M solution is 0,1 mole of solute.

Thanks!

So, writing:

0,1 M NaOH is correct and 1 M NaOH etc.

Cool

And 100 mL of 0.1 M contains 0.01 moles, 100 mL of 1 M contains 0.1 molesof solute.
