Question

A sample of nickel weighs $$6.5425 \,g$$ and has a density of $$8.8 \,g \,cm^3$$ the volume ? Report the answer to correct decimal place.

Solution
Verified by Toppr

$$Volume = \dfrac{Mass}{Density} = \dfrac{6.5425 \,g}{8.8 \,g \,cm^{-3}} = 0.74 \,cm^3$$

The result should have two significant figures because the least precise term $$(8.8)$$ has two significant figures.
