a student asked by an instructor to deliver three samples of water from a class A 25 mL volumetric pipet. the water delivered by this student is found by mass measurments to have volumes of 25.12, 25.15, and 25.13 mL. If this pipet has a balibrated volume of 25.02 mL, determine the absolute error, relative error, and % relative error for each of these results.
