# A solution has a volume of 5L and contains 20g of glucose whose molar mass is 180. What is the Molarity of the solution?

Apr 27, 2018

$0.02 M$

#### Explanation:

We need to know the moles of solute we have in the solution before finding molarity. First we need to convert the 20g of glucose to moles.

$20 \text{g" * "1mol"/"180g}$ = 0.1mol

Molarity is represented as moles of solute per unit liter of solution
Thus, it is 0.1mol/5L.

$\text{0.1mol"/"5L} = 0.02 M$
