Mass Percent Calculator

🧪 Solutions & Molarity. Use the Mass percent formula to find mass percent, solute, total: pick the value you want, type the others, and the answer updates as you go.

%mass=msolutemtotal×100\%_{mass} = \dfrac{m_{solute}}{m_{total}}\times 100
Mass percent10 %

Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.

Worked example

Find the mass percent when Solute = 10 g, Total = 100 g.

Using \%mass = msolutemtotal× 100: Mass percent = 10 %.

Frequently asked questions

What is the formula for Mass percent?

\%mass = msolutemtotal× 100.

What do the letters stand for, and what units are used?

Mass percent in %, Solute in g, Total in g.

How do you calculate mass percent?

Put the values into \%mass = msolutemtotal× 100. For example, with Solute = 10 g, Total = 100 g, mass percent = 10 %.

Can I solve for a different value?

Yes. In the calculator above, pick the circle next to any value (mass percent, solute, total) and fill in the others: it rearranges the formula for you.
