Question

If a 78.51 g stone is added to a graduated cylinder, the water level rises from 20 mL to 45 mL. What is the density of the stone?​

Answer 1

Answer:

The answer is 3.14 g/mL

Explanation:

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

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

From the question

mass = 78.51 g

volume = final volume of water - initial volume of water

volume = 45 - 20 = 25 mL

So we have

$density = \frac{78.51}{25} \\ = 3.1404$

We have the final answer as

3.14 g/mL

Hope this helps you
