Question

Aluminum has a density of 2.7 g/cm3, how much space in cm3 would 81 grams of aluminum occupy? Show steps to answering this equation.

Answer 1

30 cm³

Step-by-step explanation:

Step 1: Given data

• Density of aluminum (ρ): 2.7 g/cm³

• Mass of aluminum (m): 81 g

• Volume occupied by aluminum (V): ?

Step 2: Calculate the volume occupied by aluminum

The density of aluminum is equal to its mass divided by its volume.

ρ = m/V

V = m/ρ

V = 81 g / 2.7 g/cm³

V = 30 cm³
