Question

ariel has an object made of pure zinc with a mass of 2.6 grams. what is the objects volume if zinc has a density of 7.13 g/cm³?
density = mass/volume
2.7cm³
4.5cm³
18.5cm³
0.4cm³

Explanation:

Step1: Rearrange density formula for volume

Volume = Mass / Density

Step2: Substitute given values

Volume = $\frac{2.6}{7.13}$ $\text{cm}^3$

Step3: Calculate the result

Volume $\approx 0.365$ $\text{cm}^3\approx0.4$ $\text{cm}^3$

Answer:

D. $0.4\text{cm}^3$
