Q. What is the percent error for a measurement of 2 milliliters?If needed, round your answer to the nearest hundredth of a percent.___%
Find Error: Find the greatest possible error for 2 milliliters.Divide the smallest unit of measurement by 2.Since the problem does not specify the smallest unit of measurement, we will assume it is 1 milliliter, which is a common smallest unit for liquid measurements.21=0.5Greatest possible error: 0.5 milliliters
Calculate Percent: Calculate the percent error.We have: Measurement: 2 milliliters Greatest possible error: 0.5 milliliters Percent error = (Greatest possible error/Measurement)×100%Percent error = (0.5/2)×100%Percent error = 0.25×100%Percent error = 25%
Round Answer: Round the answer to the nearest hundredth of a percent if necessary.Since the percent error is exactly 25%, no rounding is needed.
