Answer:
6.41 %
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 = 7.80 g/cm³
error = 7.30 - 7.80 = 0.5
We have
[tex]p(\%) = \frac{0.5}{7.8} \times 100 \\ = 6.410256...[/tex]
We have the final answer as
6.41 %
Hope this helps you
