Question

1. a 2.0 kg brass monkey has a volume of 240 m³. the density of the brass monkey is (a) 56.78 kg/m³ (b) 0.00833 kg/m³ (c) 120 kg/m³ (d) 480 kg/m³ (e) none of the above

Explanation:

Step1: Recall density formula

The formula for density $
ho$ is $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 2.0\ kg$ and $V=240\ m^{3}$, then $
ho=\frac{2.0}{240}=\frac{1}{120}\approx0.00833\ kg/m^{3}$.

Answer:

B. $0.00833\ kg/m^{3}$
