Q. What is the percent error for a measurement of

25

milligrams?

\newline

If needed, round your answer to the nearest hundredth of a percent..

\newline

\newline

\_\_\_\%

Find Error Calculation: Find the greatest possible error for $25$ milligrams. $\newline$ Divide the smallest unit of measurement by $2$ . $\newline$ Since the smallest unit of measurement is not specified, we will assume it is $1$ milligram for this calculation. $\newline$ $\frac{1}{2} = 0.5$ $\newline$ Greatest possible error: $0.5$ milligrams
Calculate Percent Error: Calculate the percent error. $\newline$ We have: $\newline$ Measurement: $25$ milligrams $\newline$ Greatest possible error: $0.5$ milligrams $\newline$ Percent error = $(\text{Greatest possible error} / \text{Measurement}) \times 100\%$ $\newline$ Percent error = $(0.5 / 25) \times 100\%$ $\newline$ Percent error = $0.02 \times 100\%$ $\newline$ Percent error = $2\%$
