Question

A lead ball has a mass of 55.0 grams and a density of 11.4 g/cm3. what is the volume of the ball?

Answer 1

Answer:

Volume,$V=4.82\ cm^3$

Explanation:

Given that,

Mass of the lead ball, m = 55 grams

Density of lead ball, $d=11.4\ g/cm^3$

We need to find the volume of the ball. The formula of density is given by :

$d=\dfrac{m}{V}$

$V=\dfrac{m}{d}$

$V=\dfrac{55\ g}{11.4\ g/cm^3}$

$V=4.82\ cm^3$

So, the volume of the the lead ball is

$V=4.82\ cm^3$. Hence, this is the required solution.

Answer 2

The volume of the lead ball is 4.83 cubic centimeters.

Given the following data:

• Mass of lead ball = 55.0 grams

• Density of lead ball = $11.4\; g/cm^3$

To find the volume of the lead ball;

Density can be defined as mass all over the volume of an object.

Simply stated, density is mass per unit volume of an object.

Mathematically, the density of a substance is given by the formula;

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

Making volume the subject of formula, we have;

$Volume = \frac{mass}{density}\\\\Volume = \frac{55}{11.4}$

Volume = 4.83 cubic centimeters.

Therefore, the volume of the lead ball is 4.83 cubic centimeters.
