Question

a) a block of aluminum occupies a volume of 15.0 ml and mass of 40.5 grams. what is the density of the aluminum block?

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

We are given $m = 40.5$ g and $V=15.0$ mL. Substituting into the formula, we get $
ho=\frac{40.5}{15.0}$.

Step3: Calculate density

$
ho = 2.7$ g/mL.

Answer:

$2.7$ g/mL
