Insert the information in the form and the calculator will determine the mass percent.

What is the mass percent?

The mass percentage is a representation of the concentration of an element in a compund or component in a mixture.

How to calculate mass percent?

To calculate mass percent you should use the following formula:
wi = (mi / mtot) * 100
where:
wi = mass fraction
mi = mass
mtot = mass of solute + mass of solvent

example: Calculate the mass percent of 11g of caustic soda dissolved in 170g of water?

Using the mass percent formula the answer will be:
:
wi = (mi / mtot) * 100
wi = (1 / (170 + 11)) * 100
wi = 60.77%

Why use mass percent?

The mass percent is used as a way to express the concentration or describing the component in a specific mixture. The solution composition can be described in mass percentage which tells the mass of solute that is in a specific mass of solution.
