Question
Hi: A mixture contains 2.54 g cucalptol, 1.76 g menthol,3.21 g methyl salicylate, and 1.95 g thymol in 205.28 gwater. What is the percentage composition by mass for eachcomponent in the mixture? There are five components in themixture. Nettie's answer? Part x 100/whole Eucalptol = 2.54g x 100 = 1.18% 214.74 Menthol = 1.76g x 100 = .82% 214.74 Does this look right?

To calculate the mass percentage of the each compound inthe gives mixture,wecan determine the total mass of thecompound. Total mass of thesolution = 2.54g + 1.76g + 3.21g + 1.95g +205.28g = 214.74g Thus the mass percentage of the Cucalptol =(2.54g/214.74g)*100 =1.18% mass percentage ofmenthol = (1.76g/214.74g)*100 = 0.81% mass percentage of the methylsalicylate = 3.21g/214.74g)*100 = 1.49% mass percentage ofthymol = 1.95g/214.74g)*100 = 0.9% mass percentage ofwater = 205.28g/214.74g)*100 = 95.6%Related Questions
