Answer:
Density = 3 g/mL
Explanation:
Density of a substance can be found by using the formula
[tex]Density = \frac{mass}{volume} [/tex]
From the question
mass = 90 g
volume = 30 mL
Substitute the values into the above formula and solve for the Density
That's
[tex]Density = \frac{90}{30} \\ = \frac{9}{3} [/tex]
We have the final answer as
Density = 3 g/mL
