calculate the concentration of each solutions:
3 moles of solute dissolved in 2 liter of solution
6 moles of solute dissolved on 9 liters of solution
4 moles of solute dissolved in 3 liters of solution
moles/L = molarity.
3 moles/2 liters = ?? etc.
that is true and remember that litre is equivalent to dm^3.
you can also order the UPCO's Physical Setting CHEMISTRY... it has many helpful equations and it will make it easier to study and understand evrything... plus the book is cheap too.
