yan [13]

Answer:

<h2>Density = 2700 g/L</h2>

Explanation:

Density of a substance can be found by using the formula

Density =  \frac{mass}{volume}

From the question

volume = 0.015 L

mass = 40.5 g

Substitute the values into the above formula and solve for the Density

That's

Density =  \frac{40.5}{0.015}

We have the final answer as

Density = 2700 g/L

Hope this helps you
