Percent Solution Calculator

The percent solution calculator, which you may also refer to as the weight to volume percent calculator, is here to help you figure out how to find the concentration of a solution. You can also use it as a percent weight calculator and a percent volume calculator to determine the mass percentage and the volume percentage, respectively.

Read on if you want to discover:

• What is mass by volume percent?
• How do I find the concentration of a solution?
• How to determine mass percentage or volume percentage using this percent solution calculator.
• What could you do to increase the concentration of a solution?

And more... Let's go!

To obtain a solution, we have to add some solute to a solvent, and the mass by volume percent, or concentration, is the solute content of that solution. Solvents are usually liquid, so we can dissolve substances in them, while solutes can be virtually anything as long as they dissolve and spread evenly in a solvent.

The percent solution formula is relatively straightforward! All you need to do is follow a few steps:

1. Determine the weight (mass) of your solute. Let's take 7.8 g of sugar.

2. Dissolve the solute in your solvent and determine the overall volume of your solution. Let's assume we dissolved the sugar in some water and ended up with 62 ml of a sugar and water solution.

3. Divide the mass by the volume and multiply by 100:

   mass to volume percentage = mass of solute / volume of solution) × 100

   mass to volume percentage = (7.8 / 62) × 100 = 12.58%

Try to do it yourself! What is the concentration of a 162-milliliter solution containing 32 grams of solute? 🤔 (Spoiler alert: the answer is in the next paragraph. Don't look!)

This weight-to-volume percent calculator allows you to skip the steps above! Here's what you have to do:

1. Insert the mass of your solute. In this case, we have 32 g. (As always, you can switch between units as you please by clicking on the unit on the right-hand side of any field.)

2. Insert the volume of the solution: 162 ml.

3. The calculator immediately tells you the mass to volume percentage: 19.753%.

4. Have a look at the second section of the calculator to see the concentration in mass per volume, parts per million or billion, and custom mass per volume (for example, per 250 ml of solution). In this case, the results look as follows:

   • Mass per volume: 0.198 g/ml;
   • Parts per million: 197531 ppm; and
   • Custom mass per volume: 49.38 g per 250 ml.

This percent solution calculator can also be used as a percent weight calculator. To use this function, expand the "Weight percentage" section.

1. Double-check or insert the mass of the solute.
2. Insert the mass of the solution.
3. The percent solution calculator instantly tells you the weight percentage (also known as mass percentage).

Let's take a look at the percent by mass formula:

weight percentage = (mass of solute / mass of solution) × 100

Therefore, if you want to find the percentage by mass, you need to divide the mass of the solute by the mass of the solution obtained and then multiply by 100.

Now, you also know how to determine weight percent. But surely, it will be easier to use our percent solution calculator!

The last section of this tool allows you to calculate the volume percentage. Similarly to the percent by mass formula, to find the volume percentage, you need to divide the volume of the solute by the volume of the obtained solution and then multiply by 100.

Let's see how to calculate percent volume with our percent solution calculator:

1. Expand the "Volume percentage" section of the percent solution calculator.

2. If you have already inserted the weight of your solute and you know its density, check the checkbox at the beginning of the section. Upon entering the density, the volume of your solute will be calculated automatically. You can also insert this volume manually if you wish.

3. Double-check or insert the volume of the solution.

4. That's it! The volume percentage appears just below.

Keep in mind that this percent solution calculator is fully integrated. This means that as you type more and more information, the missing fields will become populated automatically! We suggest you try it out: expand all the sections, start inserting different data (the order doesn't matter), and look at how the tool fills in the gaps!
