In the standard deviation, the decimal place of the first non-zero digit indicates where the precision of the average ends (decimal place where the individual results deviate from each other). All your mass readings have 5-6 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.
