Answer:

The answer is 10 %

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 density = 0.7 g/cm³

error = 0.7 - 0.63 = 0.07

So we have

[tex]p(\%) = \frac{0.07}{0.7} \times 100 \\ = 10[/tex]

We have the final answer as

10%

Hope this helps you
