Question

a block of aluminum occupies a volume of 15.0 cubic cm and has a mass of 40.5 grams. what is its density?

Explanation:

Step1: Recall density formula

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

Step2: Identify given values

We are given that $m = 40.5$ g and $V=15.0$ cm³.

Step3: Calculate density

Substitute the values into the formula: $
ho=\frac{40.5\text{ g}}{15.0\text{ cm}^3}=2.7$ g/cm³.

Answer:

2.7 g/cm³
