Your solution's concentration by mass will be equal to **35.5%**.

#### Explanation:

To get a solution's concentration by mass, sometimes called *percent by mass*, or *total mass of the solution*, and multiply this ratio by 100.

So, you're dissolving **55.00 g** of potassium hydroixe in *100 g* of water. The mass of the solute will be equal to that of the potassium hydroxide.

The mass of the solution, however, will be equal to

In your case, you have

This will make the solution's concentration by mass equal to
