Question

SHOW YOUR WORK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

An experiment was conducted to find the mass of one mole of carbon atoms. The results of the experiment showed that a mole of carbon atoms had a mass of 15.78 g. The accepted value of a mole of carbon atoms is 16.00 grams. What is the percent error in this experiment?

Answer 1

1.375%

Step-by-step explanation:

Percent Error = measured value - accepted value/ accepted value x 100

Measured Value: 15.78

Accepted Value: 16.00

Work:

`(15.78-16.00)/(16.00)` * 100

`(-.22)/(16)` * 100 = -1.375

You cannot have a negative percentage. Therefore the answer is 1.375%
