Question

The accepted density of copper is 8.96 g/mL. Calculate the percent error of a student’s measurement which resulted in a density of 8.86 g/mL.

Answer 1

The answer is 1.12 %

Step-by-step explanation:

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

`P(\%) = (error)/(actual \: \: number) * 100\% \\`

From the question

actual density = 8.96 g/mL

error = 8.96 - 8.86 = 0.1

We have

`p(\%) = (0.1)/(8.96) * 100 \\ = 1.1160714...`

We have the final answer as

1.12 %
