To calculate the percent Fe in the original mixture, we need to determine the mass of Fe in the original mixture and divide it by the total mass of the mixture.Given information:- The mass of
is 5.95 g.- The mass of the ignited oxide (
) is 2.62 g.Step 1: Calculate the mass of Fe in the original mixture.The mass of Fe in the original mixture can be calculated by subtracting the mass of the ignited oxide (
) from the mass of
.Mass of Fe = Mass of
- Mass of
Mass of Fe = 5.95 g - 2.62 g = 3.33 gStep 2: Calculate the percent Fe in the original mixture.Percent Fe = (Mass of Fe / Total mass of the mixture) × 100Percent Fe = (3.33 g / 5.95 g) × 100 = 55.8%Therefore, the percent Fe in the original mixture is 55.8%.
