The density of copper is `7.8 g cm^(-3)` and its weight is `5.642 g`. Report the volume of copper to correct decimal point.

Text Solution

Verified by Experts

Volume `= ("Mass")/("Density") = (5.642 g)/(7.8 g cm^(-3))`
`= 0.7233 cm^(3) = 0.72 cm^(3)`
The result should have two significant figures because the least precise term (7.8) has two significant figures.
