Question

While inspecting some of your lab results you discover that instead of a final average of 4.55 grams you obtain a result of 4.70 grams. Based upon these results, what was your percent error?

Answer 1

To calculate the percent error, subtract the accepted value from the experimental value, take the absolute value, divide by the accepted value, and multiply by 100%.

Step-by-step explanation:

To calculate the percent error, we need to compare the experimental value with the accepted value. In this case, the experimental value is 4.70 grams and the accepted value is 4.55 grams. To calculate the percent error, we use the formula:

Percent Error = (|Experimental Value - Accepted Value| / Accepted Value) x 100%

So, the percent error is: (|4.70 grams - 4.55 grams| / 4.55 grams) x 100% = 3.30%.
