Question

the density of aluminum is 2.7g/cm. what is the volume of a piece of aluminum if its mass is 8.1 grams?​

Answer 1

Answer:

3cm^3

Explanation:

Assuming you meant 2.7g/cm^3

$density = \frac{mass}{volume}$

$2.7 \frac{g}{cm^3} = \frac{8.1g}{volume} \\ volume(2.7 \frac{g}{cm^3} ) = 8.1g \\ volume = 8.1g \times \frac{1cm^3}{2.7g} \\ volume = 3cm^3$
