Answer to Question #158058 in General Chemistry for sabrina

Question

An irregularly-shaped piece of aluminum (Al) has a mass of 73.8 grams. What is the volume in cm³ of this piece of aluminum if its density is 2.70 g/cm³?

Answer 1

Density is calculated as;

Density(g/cm³) $=\dfrac{Mass(g)}{Volume(cm^3)}$

Rearranging for volume gives;

$Volume (cm^3) = \dfrac{Mass(g)}{Density}$

$=\dfrac{73.8g}{2.70g/cm^3}$

$=27.3cm^3$
