14. Buoyancy correction - a sample appears lighter than its actual mass by an amount equal to the mass of the air it displaces.
Example: Find the true mass of water (density = 1.00 g/mL) if the apparent mass is g

18. Calibration of Volumetric Glassware
True volume = mass H2O x correction factor
Example p. 49: an empty weighing bottle had a mass of g. After water was added from a 25-mL pipet, the mass was g. The temperature was 23oC. Find the volume of water delivered by the pipet.
