Question

How many liters of water need to be added to 22 moles of `KCl` to make a 0.2 M solution?

Answer 1

Over `100*L` of water must be added.

Explanation:

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

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

And thus,
`"Volume of solution"=(22*mol)/(0.2*mol*L^-1)` `=` `??*L`
