1) Estimate the magnitude of the absoulte error and percent error in the measured sample volumes. Compare those errors to the errors that occur when measuring volumes of approximately 8mL, as is normally done in this experiment. Assume that the graduated cylinder used to measure all of the volumes has 0.1-mL graduations, 2) Based on your answer to (1), would you be more or less confident about your density measurement if you used the smaller sample volume, rather than the normal 8-mL sample? Breifly explain
