The accepted density of copper is 8.96 g/mL. Calculate the percent error of a student’s measurement which resulted in a density
uranmaximum [27]

Answer:

<h3>The answer is 1.12 %</h3>

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 = 8.96 g/mL

error = 8.96 - 8.86 = 0.1

We have

p(\%) =  \frac{0.1}{8.96}  \times 100 \\  = 1.1160714...

We have the final answer as

<h3>1.12 %</h3>

Hope this helps you
