In order to calculate the experimental percent error, we follow these steps: 1- Subtract one value from the other (order does not matter as we take absolute) 2- Divide the obtained number by the accepted or true value. 3- Multiply the fraction you got from step 2 by 100 to get the percentage of error.
Now, we will apply these steps on our problem: 1- Subtract one value from the other: 9.95 - 7.13 = 2.82 2- Divide by accepted value: 2.82 / 7.13 = 0.3955 3- Multiply by 100 to get the error percentage: error percentage = 0.3955 x 100 = 39.55%
