Purpose: The purpose of this experiment is to learn how to separate the components of a mixture and to determine the mass percent of each. Procedure: Refer to pages 15-16 of Laboratory Experiments in General Chemistry, Volume 1 by Judith Casey and Robert Tatz, Hayden McNeil Publishing, 2009-2010. Report Sheet: See attached report sheet Sample Calculations: Percent Calculation of Organic component, X: Mass of Component X 100% = %component Total mass of sample %component= (0.4258g/0.5814g)x100 = 73.24% Report Questions: 1. Total your percentages. Do they add to 100%? Answer either a or b, based on your results. b.) I recovered more than 100% I think this could be due to either disrupting the

A student heated component Z too strongly and it decomposed. Use the data given below to estimate the percent of insoluble component Z in the sample. Mass of sample 0.6048g Mass of organic component, X 0.1775g Mass of soluble inorganic component, Y 0.2193g % component X = (0.2085g/0.5943g)x100 = 35.08% % component Y = (0.2131g/0.5943g)x100 = 35.86% Estimated % of Z = 100 – (x +y) 100 – (35.08 % + 35 %) = 29.06 % Z Conclusion: In this experiment the separation of components was conducted....
