To calculate the mass percent or weight percent of a solution, you must divide the mass of the solute by the mass of the solution (both the solute and the solvent together) and then multiply by 100 to change it into percent.
Say you have a pie and want to know if you eat 1/2 of it what percentage is left. Now 1 pie - 1/2 pie = 1/2 pie So (1/2 pie) / (1 whole pie) = 1/2 Divide 2 into one and you ge â¦ t .50 To get percent move decimal place two spaces to left.In this case you get 50%.o find percentage weight loss, take your current weight, and divide it by your original weight. Then multiply this number by 100, to make it a percentage. If the resulting â¦ percentage is bigger than 100 (say, 103%), it means you have gained 3 percent of your original bodyweight.
