Question

melissa has a sample of an unknown substance. she measures the substance to mass is 13.5 grams, and its volume is 5 cm³. which metal might her sample be made of? silver density 10.5 g/cm³ copper density 8.96 g/cm³ iron density 7.87 g/cm³ aluminum density 2.7 g/cm³

Explanation:

Step1: Recall density formula

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

Step2: Substitute given values

Given $m = 13.5$ grams and $V=5$ $cm^{3}$, then $
ho=\frac{13.5}{5}=2.7$ $g/cm^{3}$.

Answer:

The metal sample might be made of aluminum as its density is closest to the calculated density of 2.7 $g/cm^{3}$ among the options provided.
