Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass = 249 g
volume = final volume of water - initial volume of water
volume = 19 - 15 = 4 mL
We have
[tex]density = \frac{249}{4} \\ [/tex]
We have the final answer as
