A student measures the mass of 8o ml of liquid in a Graduated cylinder. The cylinder alone has a mass of 50.5 g. The cylinder plus the liquid has a Mass of 70.5 g. What is the density of the liquid?

The liquid's mass is 70.5 - 50.5 g = __?

The density is (liquid mass)divided by(volume)

It's going to be a number much less than 1.00 g/cm^3. I wonder if there really are liquids that light
