Answer:
The answer is 3.14 g/mL
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume}\\[/tex]
From the question
mass = 78.51 g
volume = final volume of water - initial volume of water
volume = 45 - 20 = 25 mL
So we have
[tex]density = \frac{78.51}{25} \\ = 3.1404[/tex]
We have the final answer as
3.14 g/mL
Hope this helps you
