Question

Density can be calculated by dividing mass by volume. \(0.20 \pm 0.02{\text{ g}}\) of a metal has a volume of \(0.050 \pm 0.005{\text{ c}}{{\text{m}}^{\text{3}}}\). How should its density be recorded using this data?

A.     \(4.0 \pm 0.025{\text{ g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)

B.     \(4.0 \pm 0.8{\text{ g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)

C.     \(4.00 \pm 0.025{\text{ g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)

D.     \(4.00 \pm 0.8{\text{ g}}\,{\text{c}}{{\text{m}}^{ - 3}}\)
