Question

The accepted value of density of a penny is 7.2 g/mL. You are testing this in a lab. Your results show that the total water displacement was 3.4 x 10-2 L, the total weight of the penny is 2.5 g. What is your experimental value for the density of the penny​

Answer 1

d = 0.0735 g/mL

Step-by-step explanation:

Given that,

The accepted value of density of a penny is 7.2 g/mL

Mass of the penny, m = 2.5 g

Volume,
`V=3.4* 10^(-2)\ L`

Since, 1 L = 1000 mL

`3.4* 10^(-2)\ L=0.034\ L=34\ mL`

The density of the experiment value is given by :

Density = mass/volume

So,

`d=(2.5\ g)/(34\ mL)\\\\d=0.0735\ g/mL`

Hence, the experimental value for the density of the penny​ is 0.0735 g/mL.
