…of lead three times. The density of lead is actually 11.34 g/cm3. Considering all of the results, which person's results were accurate? Which were precise? Were any both accurate and precise? a) Rachel: 11.32 g/cm3 , 11.35 g/cm3 , 11.33 g/cm3 b) Daniel: 11.43 g/cm3 , 11.44 g/cm3 , 11.42 g/cm3 c) Leah: 11.55 g/cm3 , 11.34 g/cm3 , 11.04 g/cm3 4) Perform these calculations, following the rules for significant figures. a) 26 x 0.02584 = b) 15.3 / 1.1 = c) 782.45 - 3.5328 = d) 63.258 + 734.2 = 1-3 The Language of Physics
