Q. What is the greatest possible error for a measurement of 5milligrams?____ milligrams
Determine Precision: Determine the precision for the measurement of 5 milligrams.Since the measurement is given as 5 milligrams without any decimal or further precision, we can assume that the measurement is precise to the nearest milligram.Precision: 1 milligram
Calculate Error: Calculate the greatest possible error based on the precision.The greatest possible error for a measurement is half of the unit of precision.Greatest possible error =2Precision=21 milligram=0.5 milligrams
