Density of Unknown Liquid TRIAL 1 TRIAL 2 Mass of beaker (g) 29.555 g N/A Mass of beaker and liquid (g) 33.464 g 3.939 g Mass of liquid (g) 3.909 g 3.939 g Volume of liquid (mL) 5.0 mL 5.0 mL Density of liquid (g/mL) „78 g / mL .79 g / mL Average density of liquid (g/mL) .79 g / mL Identity of liquid Ethanol [density = 0.789 g/mL] 2. Density of Ethanol: Consider the data and results from the density of ethanol determination. Now focus on the average absolute error associated with the calculated average density of ethanol. How does this error compare to the average absolute error for density of zinc? Provide a brief explanation as to why it is higher or lower than the error on the density of zinc.
