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

Jun 7, 2016

Over $100 \cdot L$ of water must be added.

Explanation:

$\text{Concentration"="Moles of solute"/"Volume of soluion}$

$\text{Volume of solution"="Moles of solute"/"Concentration}$

And thus,
$\text{Volume of solution} = \frac{22 \cdot m o l}{0.2 \cdot m o l \cdot {L}^{-} 1}$ $=$ ??*L
