How can I calculate percent concentration by mass?
1 Answer
The formula that you would use is:
Concentration (%) = (mass of solute / mass of solution) x 100
For example, suppose you dissolve 15 grams of sugar in 200 grams (ml) of water. What is the mass percent concentration of the solution?
concentration(%) = (15 grams of sugar / 15 + 200 grams of sugar and water) X 100
concentration (%) = (15 / 215) X 100 = 6.98% sugar
