A piece if stone has a mass of 24.595 grams and a volume of 5.34 cm ^3. What is the density of the stone
Rudik [331]

Answer:

The answer is

<h2>4.61 g/cm³</h2>

Explanation:

The density of a substance can be found by using the formula

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

From the question

mass of stone = 24.595 g

volume = 5.34 cm³

The density of the stone is

density =  \frac{24.595}{5.34}  \\  = 4.605805243...

We have the final answer as

<h3>4.61 g/cm³</h3>

Hope this helps you
