Question

A 75 mL solid is estimated by a student to be 81 mL. Calculate the percent error.

Answer 1

8 %

Step-by-step explanation:

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

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

From the question

error = 81 - 75 = 6 mL

actual volume = 75 ml

We have

`p(\%) = (6)/(75) * 100 \\ = (2)/(25) * 100 \\ = 2 * 4 \\ = 8 \: \: \: \: \: \: \: \:`

We have the final answer as

8 %
