# What is the molarity of 2 moles of a compound dissolved in 4 L of water?

Jun 21, 2017

M = 0.5 mol/L

#### Explanation:

Molarity is the ratio of moles of solute to liters of solution.

$M = \text{moles solute"/"litres solution}$

$\text{2 mol"/"4 L" = "0.5 mol/L}$

The symbol for molarity is mol/L.
