What volume of a #1.5*mol*L^-1# solution is required to deliver a #3.0*mol# quantity of solute?
Look at the problem dimensionally:
we know that
We get an answer in
In order to use these quotients, you have to remember the basic definition:
To actually work it out, use the simple relationship
Where M is molarity (or concentration) in moles per
Then simply rearrange for V, so
