Final answer:
To find the mass of aluminum foil with a volume of 48.9 cm³, multiply the volume by its density, 2.70 g/cm³, resulting in a mass of approximately 132.03 grams.
Step-by-step explanation:
The mass of aluminum foil can be calculated by multiplying its volume by its density. The density of aluminum is a known constant 2.70 g/cm³. Therefore, to find the mass of aluminum foil with a volume of 48.9 cm³, we use the formula:
Mass (g) = Density (g/cm³) × Volume (cm³)
By substituting the given values into the formula, we obtain:
Mass (g) = 2.70 g/cm³ × 48.9 cm³
The resulting mass of the aluminum foil is:
Mass (g) = 132.03 g
This calculation shows that a piece of aluminum foil with a volume of 48.9 cm³ will have a mass of approximately 132.03 grams.
