Question

What is the percent error for the experiment if the actual density is
2.49g/mL but the experimental value is 1.47 g/mL?

Answer 1

Answer:

The answer is 40.96%

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 = 2.49g/mL

error = 2.49 - 1.47 = 1.02

We have

$p(\%) = \frac{1.02}{2.49} \times 100 \\ = 40.96385542...$

We have the final answer as

40.96 %
