Answer:

3.31 g/mL

Step-by-step explanation:

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


density = (mass)/(volume) \\

From the question

mass = 23.2 g

volume = final volume of water - initial volume of water

volume = 62 - 55 = 7 mL

We have


density = (23.2)/(7) \\ = 3.314285

We have the final answer as

3.31 g/mL

Hope this helps you
