Question

A 50.0 mL graduated cylinder has a mass of 67.6 g. When it is filled with an unknown liquid to the 38.8 mL mark, the cylinder and liquid combined have a mass of 119.4 g. Calculate the density of the liquid in g/cm3. (1 mL = 1 cm3.)
nm, the answer is 1.34
119.4 g = mass cylinder + liquid
-67.6 g = mass empty cylinder
---------
51.8 g = mass liquid
density liquid = mass/volume = ?
