Jamie found the mass of an object in the lab to be 4.55 g. His teacher informed him that the actual mass was 5.0 g. What is Jamie's percent error? (Round your final answer appropriately to the correct number of significant figures and include units!

-9%

Step-by-step explanation:

First you subtract the measured and the accepted value.

(Measured value: the value you get in the lab)

(Accepted value: the actual value)

After you subtract 4.55-5.0, you should get (negative) -0.45

Take -0.45 and divide that with 5.0 you should get -0.09

Multiply -0.09 by 100 and you get your percentage error

= -9%
