Question

+

Answer 1

Answer:

The answer is 41.05 %

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

actual density = 0.95 g/mL

error = 0.95 - 0.56 = 0.39

So we have

$p(\%) = \frac{0.39}{0.95} \times 100 \\ = 41.0526315...$

We have the final answer as

41.05 %

Hope this helps you
