Answer:

The answer is 10.42 %

Step-by-step explanation:

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

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual mass = 240 g

error = 265 - 240 = 25

So we have

[tex]p(\%) = \frac{25}{240} \times 100 \\ = 10.41666666...[/tex]

We have the final answer as

10.42 %

Hope this helps you
