Step-by-step explanation:
Sig fig definition: certain digits+ 1 uncertain digit
graduated cylinder going up by ones. We should estimate the tenths place. The meniscus looks about halfway between 5 and 6 mL, so you can estimate the tenths around that point.
D=M/V
D= 15.20 g/(38.29 mL-26.35 mL)= 1.273 g/mL
estimated to around 4 sig figs like given values.
