1) The gold will occupy a volume of 2.99 dm³.
[tex]\text{Volume = 17 200 g} \times \frac{\text{1 cm}^{3}}{\text{5.75 g}} = \text{2990 cm}^{3} = \textbf{2.99 dm}^{3}\\[/tex]
2) The density of the olive oil is 0.850 g/cm³.
[tex]\text{Density} = \frac{\text{mass}}{\text{volume}} = \frac{\text{425 g}}{\text{500 cm}^{3}}= \textbf{0.850 g/cm}^{3}[/tex]
3) The mass of the silver is 10.4 kg.
[tex]\text{Mass} = \text{987 cm}^{3} \times \frac{\text{10.5 g} }{\text{1 cm}^{3 }} = \textbf{10 400 g = 10.4 kg}\\[/tex]
