Question

A chemist has a block of aluminum metal (density is 2.7 g/mL). The block weighs 2.3 g. What is the volume, in mL, of the aluminum block?

Answer 1

0.85 mL

Step-by-step explanation:

Step 1: Given data

• Density of aluminum (ρ): 2.7 g/mL

• Mass of the aluminum block (m): 2.3 g

• Volume of the aluminum block (V): ?

Step 2: Calculate the volume of the aluminum block

Density is an instrisic property. It is equal to the mass of the block divided by its volume.

ρ = m/V

V = m/ρ

V = 2.3 g/(2.7 g/mL)

V = 0.85 mL
