A rock weighing 75.0g is placed in a graduated cylinder displacing the volume from 31.4 ml to 36.5ml. What is the density of the
denis-greek [22]

Answer:

<h2>14.71 g/cm³</h2>

Explanation:

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

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

volume = final volume of water - initial volume of water

volume = 36.5 - 31.4 = 5.1 mL

But

1 mL = 1 cm³

5.1 mL = 5.1 cm³

From the question we have

density =  \frac{75}{5.1}  \\  = 14.705882..

We have the final answer as

<h3>14.71 g/cm³</h3>

Hope this helps you
