Separating a Mixture of Compounds Kenneth M. Colón CHM-1025c Instructor: Dr. Daeri Tenery October 30 th , 2019 Separating a Mixture of Compounds Experiment 1: Sublimation of ammonium chloride (NH 4 Cl) 1. Calculate and record the following (in grams): a mass of the empty evaporating dish (g) 76.000g b mass of the evaporating dish plus the powder mixture sample (g) 86.000g c mass of the sample, b minus a (g) 10.000g d mass of the evaporating dish and the remaining contents after sublimation (g) 84.778g e Subtract (d) from (b) to obtain the mass of NH 4 Cl in the sample (g) 1.222g Experiment 2: Filtration of Sand (SiO 2 ) 91. Calculate and record the following (in grams): a mass of an empty beaker 85.000g b mass of the beaker with the SiO 2 after decanting 91.158g c mass of the SiO 2 (b minus a) 6.158g Experiment 3: Calculation of the Sodium Chloride (NaCl) Content and Evaporation 1. Calculate and record the following (in grams): a mass of the beaker with NaCl after boiling away water (g) 87.620g b measured mass of NaCl after boiling away water (a minus the mass of the beaker from Experiment 2) (g) 2.620g

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
