Problem

A solid metal sphere has a mass of

1.250\times10^{4}\,\text{g}

and occupies a volume of

4.7\times10^{2}\,\text{cm}^{3}

. (i) Find the density of the metal in

\text{g cm}^{-3}

. (ii) Report the density with the correct number of significant figures. (iii) Convert the density obtained in part (ii) to SI units (

\text{kg m}^{-3}

) and express the result in scientific notation.
