abelkoontz Posted August 10, 2016 Report Share Posted August 10, 2016 So I used 1 Mole of HCl, which came in a bottle. I used 20 mL of that. I made 0.75 moles of it by using 15 ml of HCl and 5 ml of water etc till 0.25 moles How do I work out the concentration of it? in mol.dm-3 I did mol/vol which was 1/0.02 = 50?!?!? im so confused please help Reply Link to post Share on other sites More sharing options...

I have another dilution example here: 1 Reply Link to post Share on other sites More sharing options...
