Jr. High Pressure Challenge Question

A small flask has a mass of 22.71 g. When it is filled with water the total mass is 153.38 g. When it is filled with milk the total mass is 157.67 g. What is the density of milk?

Let v be the volume of the flask.
densitywater= 1g/cm^3 you can be more accurate than that.
So, find the volume of water:
volume=mass/density=(153.3822.71)g/1g/cm^3 you figure that out.
density milk= (157.6722.71)g/volumeabove
