Density and mass percent of C & H sugar solutions Angelina Borg-Malec Data, Calculations and Results Part I – Creating a calibration curve of standard sugar solutions a. Preparing standard sugar solutions (15 points) Solution Mass sugar Mass solution % by mass (w/w %) mass sugar/(mass sugar + mass water) A 1.984g 40.379g 4.901g B 4.037 43.203g 9.364g Cup A + solution = g Cup B + solution = g b. Determining densities of the standard sugar solutions (15 points) Solution Mass empty 50 mL beaker Trial 1 Trial 2 Trial 3 Avg mass of 10.0 mL Density g/mL A 34.214g 9.742g 10.019g 9.779g 9.846g 0.984g/ml B 34.314g 10.905g 10.505g 10.827g 10.745g 1.075g/ml example calculation: 9.864 avg g/10ml. 9.864/10 = 0.984g/ml
