Whether you're trying to make your homework go by a bit faster, forgot your scientific calculator in class, or are just trying to check your work, our molarity calculator is the way to go.
With more than 12 units, our molarity calculator takes the guesswork out of conversions. It's easy to use and guarantees the most accurate answers.
Have questions about the molarity of a solution? Check out this article for a detailed FAQ session on what molarity is and why it's important.
A molarity concentration calculator does the difficult conversions for you.
Sometimes those hard conversions can take more than 20 minutes for just one problem when you try to do it on paper.
Aside from the glaring fact that conversions can be difficult to tackle, our conversion calculator can also be used for personal, business, or commercial purposes.
Whatever the reason, having a calculator is favorable to solving molarity concentration problems.
Using our molarity calculator is as easy as opening a new browsing tab. So, how does it work? The steps are simple:
The final conversion result will be displayed in the output box. Want to change between units? Just hit swap!
Molarity is defined as the concentration of a solution, expressed as the number of moles of solute per liter of solution.
Let's go over that in a way that is easier to understand.
The molarity of a solution is simply the measurement of the concentration of the solution at a molecular level.
It is important for scientists to know the molarity of a solution because the concentration of a solution changes its properties.
Water boils at 212°F. If you add salt to the water, it will elevate the boiling point and lower the freezing point.
Have you ever tried to measure the amount of salt you put into a pot of water after it's dissolved? It's nearly impossible.
The salt looks like it's totally gone, but it's elements are definitely still there, and they're affecting the water's properties.
The smallest changes can make the biggest differences, and chemists need a way to measure those changes.
This is why we have molarity, so we can calculate the concentration of a solution from its molecular level.
Molarity is represented by "M". The standard unit is measured in mol/L, though you'll likely encounter many different measurements.
Moles can be measured in many different unit sizes. Think about an easier unit of measurement, like the meter, for example. Meters measure distance.
Just like meters, moles use conversions such as kilomole or millimole and cm3, mm3 or m3. Our molarity concentration calculator is equipped to convert between all of these units, and more.
When converting molarity you may have to use certain conversion factors for the amount of solute and the volume. Let's go over an example.
Let's say you need to convert 0.5 mol/L to mmol/m3. The conversion factor you'll use is 106.
= 0.5 mol/L x 106
= 500,000 mmol/m
Calculating molarity can be done on paper, just like any math problem. While you may have to do it by hand in certain situations, there's no reason why you can't use a calculator to help you with your work.
Even if you choose to go the pencil and paper route, our molarity calculator is an easy way to check the accuracy of your work.
To find molarity, we take the number of moles in a solute and divide by the volume of the solution in liters.
It is written as such:
Molarity can be calculated using moles and volume, mass and volume, or moles and milliliters.
Using the periodic table, you can find the molar mass of a solution.
Start by finding out the molecular formula of the molecule.
As an example, glucose is C6H12O6
Establish the atomic mass of each element in the molecular formula using a periodic table.
In the case of glucose:
Next, you'll multiply the atomic mass of each element by the number of atoms of that element in the molecule. This is the subscript number next to each element symbol in the molecular formula.
So for glucose (C6H12O6) you would do the following:
Carbon = 12.0107 x 6
= 72.0642
Hydrogen = 1.00794 x 12
= 12.09528
Oxygen = 15.999 x 6
= 95.994
Add the resulting figures together to determine the compound's molecular mass.
Continuing with the above example, glucose has a molecular mass of 180.15348.
glucose = 72.0642 + 12.09528 + 95.994
= 180.15348
