B. Density of Unknown Liquid-Graphical Method Mass and buret readings must first be corrected by subtracting the mass of the empty beaker and the buret reading before the addition of any unknown into the beaker. Corrected data should be tabulated below. 1. Corrected mass and volumes after each addition of unknown Mass Volume a. After first addition of unknown b. After second addition of unknown C. After third addition of unknown d. After fourth addition of unknown e. After fifth addition of unknown 2. Attach your graph of mass versus volume data. Be sure you have carefully fol- lowed the instructions on graphing in the appendix of this laboratory manual Failure to follow the instructions will result in a substantial reduction in your grade. 3. Calculation of density of unknown liquid from graph. Show your calculation of the slope of the line from your graph in the space below. Make sure your graph clearly shows the two points on the line used to determine the slope. C. Table of Results Unk. # Density Ave. Dev. % Dev.
