A student determines the density of a liquid by recording its mass and volume. The measurements are summarised below: mass of empty beaker $= (20 \pm 1)\,\text{g}$ mass of beaker + liquid $= (70 \pm 1)\,\text{g}$ volume of liquid $= (10.0 \pm 0.6)\,\text{cm}^3$ He works out the density of the liquid correctly as $5.0\,\text{g cm}^{-3}$. What uncertainty should be assigned to this value?
- A$0.3\,\text{g cm}^{-3}$
- B$0.5\,\text{g cm}^{-3}$
- C$0.6\,\text{g cm}^{-3}$
- D$2.6\,\text{g cm}^{-3}$
