Question

A piece of copper metal has volume 20cm³ having mass 63g. find the density of copper​

Answer 1

formula used :

density = $\frac{mass}{volume}$

so, density of copper here = given mass of copper ÷ volume of the copper taken = $\frac{63 }{20}$ $g$ $cm^{-3}$ = $3.15$ $g$ $cm^{-3}$

Therefore, the density of the given copper metal will be  $3.15$ $g$ $cm^{-3}$ .
