Final answer:
To find the mass of the asphalt with a volume of 25 cm³ and a density of 2 g/cm³, multiply the density by the volume, resulting in a mass of 50 grams.
Step-by-step explanation:
The student is asking how to calculate the mass of a piece of asphalt with a known volume and density. According to the formula for density, density (D) = mass (m)/volume (V), the mass of an object can be calculated by multiplying its density by its volume. Given that the density of the piece of asphalt is 2 grams per cubic centimeter (g/cm³) and the volume is 25 cubic centimeters (cm³), the mass can be found by multiplying these two values together.
To find the mass (m) of the asphalt, use the formula:
m = density × volume
m = 2 g/cm³ × 25 cm³
m = 50 grams
Therefore, the mass of the piece of asphalt is 50 grams.
