Answer:
The answer is
11.25 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 = 45 g
volume = 4 mL
Substitute the values into the above formula and solve for the density
We have
[tex]Density = \frac{45}{4} [/tex]
We have the final answer as
11.25 g/mL
