257 250ml III.Determination of the Density of an Irregular Shaped metal (aluminum pellets) Trial 1 Trial 2 Trial 3 25.0 a. Mass (graduated cylinder + water), 99.379 b. Volume of water in graduated cylinder (before addition of solid sample), ml c. Mass (graduated cylinder + water + pellets), g 105.85g / 110479 / 116.219) d. Volume of water in graduated cylinder after addition of Al-pellets, ml 27.5 ml 29-Im c. Mass of Al-pellets, (line c-line a), g 31.0mL f. Volume of Al-pellets (line d-line b), mL g. Density, d = m/V, (line e/line f), (g/cm) h. Average density, d d = (di + d2 + da)/3, (g/cm) i. Reference density of Al (Table 1) = j. Percent Error,% (use error formula) Are your results accurate and precise? Briefly explain. Please print out a copy of your prepared graph and staple it to your report. Record the following information. 1. The equation of the least-squares straight line (trendline) 2. The value of the slope - 3. Percent error of density from reference value (show your calculations below)
