How do you calculate percent by mass?
Divide the mass of the element by the total mass of the compound and multiply by 100. This will give you the mass percent of the element. Example 1: mass percent = (2.01588/18.01528) x 100 = 0.11189 x 100 = 11.18%.
How do you find the percent by mass?
Mass percentage is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100%.
- Also Known As: mass percent, (w/w)%
- mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100.
- mass percent = (grams of solute / grams of solute plus solvent) x 100.
