Best ResponseYou've already chosen the best response.0\[V_1M_1=V_2M_2\]\[(1.00L)(1.0M)=V_2(2.0M)\]\[1.00mol=V_2(2.0M)\]/2.0M /2.0M\[.5L=V_2\]Chemistrty :D

Best ResponseYou've already chosen the best response.0I think so, what's 1.0%(w/v) is that the same as Molarity?

Best ResponseYou've already chosen the best response.0It stands for (mass/volume)= [Mass of solute (g) / Volume of solution (ml)] x 100

Best ResponseYou've already chosen the best response.0How does the 1.0% come in? Is it 1g/L?

Best ResponseYou've already chosen the best response.0Is that 2.0 mols of NaOH or 2.0 Molarity of NaOH?

Best ResponseYou've already chosen the best response.0It's 2.0 molarity (mol/liter)

Best ResponseYou've already chosen the best response.0I got\[2.0molNaOH/1L \times39.998g NaOH/1mol \times 1000mg/1g \times 1ml/1mg \times 1L/1000ml\]All my units cancel, and I'm left with\[79.996\]So now I'm confused.

Best ResponseYou've already chosen the best response.0Haha, this looks like my answer. I am going on two hours of trying to figure this one out. I think I will just combine our answers and turn that in :) Thanks for all of your help!!! I really, really appreciate it!
