What percentage by weight of the 1.255 kg powder is aspirin?

Explanation:
Weight percent is the fraction of the total mass that a component represents, expressed as a percent. To find the weight percent of aspirin in a powder, multiply the total powder mass by the fraction that is aspirin: percent = (mass of aspirin / total mass) × 100. Here, if the total powder mass is 1.255 kg and the aspirin portion corresponds to 0.60 of that total, then the aspirin mass is 0.60 × 1.255 kg = 0.753 kg. So the percentage by weight of aspirin is (0.753 / 1.255) × 100 ≈ 60%. The remaining mass is 1.255 − 0.753 = 0.502 kg of other ingredients.
