#### Explanation:

To find the molarity, the following equation must be used:

We are given the mass and volume of the solution, but both have bad units.

The mass of

Now we can convert 225 mL into L by multiplying 225 by 0.001 to obtain 0.225L.

All we do now is divide the number of moles by the volume to acquire the molarity:

**1.50 M**
