Final answer:
The mass of the rock sample is calculated by multiplying its density (3.2 g/cm³) by its volume (1.2 cm³), resulting in a mass of 3.84 g. The correct answer choice is C. 3.84 g.
Step-by-step explanation:
To calculate the mass of the rock sample, you can use the formula for density, which is mass divided by volume. The question provides the density of the rock sample as 3.2 g/cm³ and the volume as 1.2 cm³. Using the formula:
Density = Mass/Volume
we rearrange it to find the mass:
Mass = Density × Volume
Substituting in the given values:
Mass = 3.2 g/cm³ × 1.2 cm³
Mass = 3.84 g
Hence, option C with a mass of 3.84 g aligns as the accurate solution, showcasing how density and volume relate to determine the mass of the given rock sample.
