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

Answer:

The answer is

4.70 %

Explanation:

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

$

P(\%) = \frac{error}{actual \: \: number} \times 100\%$

From the question the

actual volume = 36.2 mL

error = 36.2 - 34.5 = 1.7

The percentage error is

$P (\%) = \frac{1.7}{36.2} \times 100 \\ = 4.69613259668...$

We have the final answer as

4.70 %

Hope this helps you
