Question

The density of aluminum is 2.70 g/mL. What is the volume in mL of of a cube of Al that has a mass of 346 g? (remember significant figures and to include the units of mL in your answer)

Answer 1

`V=128mL`

Step-by-step explanation:

Density is expressed by the relationship between mass and Volume of a substance:

`d=(m)/(V)`

Solving for the Volume V:

`V=(m)/(d)`

Replacing values:

`V=(346g)/(2.70(g)/(mL))`

`V=128mL`

Answer 2

The volume of the cube is 1.28 mL.

V = 346 g Al × (1 mL Al/2.70 g Al) = 1.28 mL Al
