A flask weights 46.8 g when it is empty and
121.6 g when filled with water. When the
same flask is filled with another liquid, the
mass is 91.2 g. What is the density of the
second liquid?

1. You must first find the volume of the flask. Do that with the water.
121.6 g = mass flask + water
- 46.8 g = mass flask empty
----------
74.8 = mass water.
density of water is 1.00 g/mL; therefore,
m = volume x density
74.8 = volume x 1.00 g/mL
volume = 74.8 mL.

Then find mass of the other liquid and use mass = volume x density to solve for density of the other liquid.
