Question

Bob is in lab and experimentally receives a volume of 34.5 mL for a copper plate. The actual volume is 36.2 mL. What is his percent error?

Answer 1

The answer is

4.70 %

Step-by-step explanation:

The percentage error of a certain measurement can be found by using the formula

`</p><p>P(\%) = (error)/(actual \: \: number) * 100\% \\`

From the question the

actual volume = 36.2 mL

error = 36.2 - 34.5 = 1.7

The percentage error is

`P (\%) = (1.7)/(36.2) * 100 \\ = 4.69613259668...`

We have the final answer as

4.70 %

Hope this helps you
