# How can I calculate the amount of solute in a solution?

##### 1 Answer

Hello, and thanks for the solutions question.

There are several ways to determine the amount of solute in a solution.

One method is using molarity (most often method used in chemistry). The equation for molarity is:

Molarity = moles of solute/liters of solution.

If you know the molarity (concentration) of a solution and the total volume of the solution (make sure it is in liters), you can determine the number of moles of solute. You may then need to convert the moles of solute to grams.

Another method of determining the amount of solute in a solution is by percent by mass. The equation used for this is:

Mass percent = (mass of solute/mass of solution) X 100%

A third method of determining the amount of solute in a solution is percent by volume. The equation for this is:

Percent by volume = (volume of solute/ volume of solution) X 100%

I do hope this answers your question. Have a wonderful day!
