# Problem: A sample of tetrachloroethylene, a liquid used in dry cleaning that is being phased out because of its potential to cause cancer, has a mass of 40.55 g and a volume of 25.0 mL at 25 oC. What is its density at this temperature?

###### FREE Expert Solution

We are asked to determine the density of tetrachloroethylene that has a mass of 40.55 g and a volume of 25.0 mL at 25°C.

Recall that density is the ratio of the mass and volume of an object:

$\overline{){\mathbf{density}}{\mathbf{=}}\frac{\mathbf{mass}}{\mathbf{volume}}}$
