A substance has a volume of 20 mL and a density of 2.5 g/mL. What is its mass?

mass = 50 g

Explanation:

Density of a substance can be found by using the formula

From the question

Density = 2.5 g/mL

volume = 20 mL

To find the mass substitute the values into the above formula and solve for the mass

That's

Making mass the subject we have

mass = Density × volume

mass = 2.5 × 20

We have the final answer as

mass = 50 g

Hope this helps you
