An environmental testing laboratory is about to begin testing water for chromium. The company's scientists learn to perform the chromium assay and test their skills by assaying commercially prepared standards with known chromium concentrations. The scientists want to be able to guarantee their customers that they will be able to analyze chromium in samples with less than 2% error. In one assay, a measurement of 0.91 g/L is obtained. The actual concentration of chromium in the standard is 1.00 g/L. What is the percent error for this measurement? Based on this result, have the scientists met their goal for accuracy?
