The percent error in the measurement of vitamin C amount by the student is 31.6%.
PERCENTAGE ERROR:
- The percentage error of a measurement can be calculated by dividing the difference between the exact value and the approximate value, by the exact value and then multiplied by 100. That is;
- % error = (exact value - measured value)/exact value × 100
- In this question, a student measured the amount of vitamin C in 200 mL of orange juice as 65 mg. The label on the carton stated the amount was 95 mg. The percent error can be calculated thus:
% error = (95 - 65)/95 × 100
% error = 30/95 × 100
% error = 31.6%.
Therefore, the percent error in the measurement of vitamin C amount by the student is 31.6%.
