Question

an ebony carving has a mass of 273 g and a volume of 207 cm³. express your answer with the appropriate units. part b a 143 cm³ sample of tin has a mass of 0.104 kg. express your answer with the appropriate units.

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Calculate density of tin

Given $m = 0.104\ kg=104\ g$ and $V = 14.3\ cm^{3}$, then $
ho_{tin}=\frac{104\ g}{14.3\ cm^{3}}\approx7.27\ g/cm^{3}$.

Step3: Calculate density of ebony

Given $m = 273\ g$ and $V = 207\ cm^{3}$, then $
ho_{ebony}=\frac{273\ g}{207\ cm^{3}}\approx1.32\ g/cm^{3}$.

Answer:

Density of tin: $7.27\ g/cm^{3}$; Density of ebony: $1.32\ g/cm^{3}$
