Question

a teacher performing a demonstration find that a piece of court displaces 23.5 ml of water . the piece of cork had a density of 5.7 grams. what is the density of the cork

Answer 1

We are asked to determine the density of the cork. To do that we will use the following formula:

`D=(m)/(V)`

Where:

`\begin{gathered} D=\text{ density} \\ m=\text{ mass} \\ V=\text{ volume} \end{gathered}`

The volume of the cork is the same as the volume that it displaced of water, therefore, we have:

`V=23.5ml`

Now, we substitute the values and we get:

`D=(5.7g)/(23.5ml)`

Solving the operations:

`D=0.24(g)/(ml)`

Therefore, the density of the cork is 0.24 g/ml.
