liquid densities. It has a volume of 25 cc, and a mass of 17.24 g when it is full of air. When filled with a liquid of unknown density, its mass = 45.00 g. What is the density of this liquid? How large an error do we make if we ignore the mass of the air that was in it when we weighed it and found m = 17.24 g?

Question

The mass of pyncnometer including air is 17.27 g. The mass of pyncnometer without air is 17.24 g.

THE ANSWER IS 1.110 g/ cm and an error of 0.1%!!!

A special-purpose laboratory glassware, pyncnometer, is used to measure liquid densities. It has a volume of 25 cc, and a mass of 17.24 g when it is full of air. When filled with a liquid of unknown density, its mass= 45.001 g. What is the density of this liquid? How large an error do we make if we ignore the mass of the air that was in it when we weighed it and found m = 17.24 g? piece of called a
