Question

A piece of metallic aluminium with a mass of 10.044 g was found to have a volume of \({\text{3.70 c}}{{\text{m}}^{\text{3}}}\). A student carried out the following calculation to determine the density.

\[{\text{Density (g}}\,{\text{c}}{{\text{m}}^{ - 3}}{\text{)}} = \frac{{10.044}}{{3.70}}\]

What is the best value the student could report for the density of aluminium?

A.     \({\text{2.715 g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)

B.     \({\text{2.7 g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)

C.     \({\text{2.71 g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)

D.     \({\text{2.7146 g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)
