Question

What is the resultant concentration when a `30*mL` of a `2.0*mol*L^-1` are diluted to a new volume of `150*mL`?

Answer 1

`"Concentration"="Moles of solute"/"Volume of solution"`

Explanation:

And we simply have to work the quotient:

`(30xx10^-3*Lxx2.0*mol*L^-1)/(150xx10^-3L)=??mol*L^-1`.

This is dimensionally consistent; `(30*mLxx2.0*mol*L^-1)=(30xx10^-3Lxx2.0*mol*L^-1)` gives me an answer in `mol`. And, the quotient gives me an answer in `mol*L^-1`.
