In the standard deviation, the decimal place of the first nonzero digit indicates where the precision of the average ends (decimal place where the individual results deviate from each other). All your mass readings have 56 significant figures, so one might expect a standard deviation of approximately 0.0001 g/mL for a general solid. Briefly explain why we typically see standard deviations of 0.01 g/mL for the density of the Unknown solid.
