Question

an unknown piece of metal is found to have a mass of 35 g and a volume of 5 cm³. based on the chart provided, what type of metal is this most likely to be?

metal	density (g/cm³)
titanium	4.51
zinc	7.14
lead	11.34

○ zinc
○ lead
● titanium
○ aluminum

Explanation:

Step1: Recall density formula

Density ($
ho$) is calculated as $
ho = \frac{\text{mass (}m\text{)}}{\text{volume (}V\text{)}}$.

Step2: Substitute values

Given $m = 35\ \text{g}$ and $V = 5\ \text{cm}^3$, substitute into the formula: $
ho=\frac{35}{5}=7\ \text{g/cm}^3$.

Step3: Compare with chart

Check the density values in the chart: Aluminum (2.7), Titanium (4.51), Zinc (7.14), Lead (11.34). The calculated density (7) is closest to Zinc's density (7.14).

Answer:

A. Zinc
