Question

identifying materials by their densities
metal | density (g/cm³)
aluminum | 2.64
iron | 7.50
lead | 11.34
you have discovered a meteorite that seems to be metallic. its mass is 370 g, and you calculate the volume to be 50 cm³. based on the three values provided, which metal would most likely match the composition of the meteorite?
○ aluminum
○ iron
○ lead
○ none of these (density is less than 1.0)

Explanation:

Step1: Calculate the density of the meteorite

The formula for density is $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume.
Given $m = 370\ g$ and $V=50\ cm^{3}$, then $
ho=\frac{370}{50}$.

Step2: Simplify the density calculation

$\frac{370}{50}=7.4\ g/cm^{3}$

Answer:

iron
