The calculated density of an object with a mass of 25.05 g and a volume of 12.8 mL is 1.96 g/mL. Keeping significant figures in mind, why is it correct to report this density as 1.96 g/mL?
Density is found by
Select...
the mass by the volume. Therefore, the reported value should contain the same number of significant figures as the
Select...
. In this case, that is the starting measurement with
Select...
total significant figures instead of the one with
Select...
significant figures.
