Answer:
The answer is 10 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 = 300 g
volume = final volume of water - initial volume of water
volume = 40 - 10 = 30 mL
We have
[tex]density = \frac{300}{30} = \frac{30}{3} \\ [/tex]
We have the final answer as
10 g/mL
Hope this helps you
