Q. What is the greatest possible error for a measurement of 8milligrams?____ milligrams
Determine precision: Determine the precision for the measurement of 8 milligrams.Since the measurement is given as a whole number without any decimal or fractional part, we can assume that the precision is 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
