Question

If the observed value for a density is 0.80 g/mL and the accepted value is 0.70 g/mL what is the percent error?

Answer 1

The answer is 14.29 %

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 = 0.70 g/mL

error = 0.8 - 0.7 = 0.1

So we have

`P(\%) = (0.1)/(0.7) * 100 \\ = 14.285714...`

We have the final answer as

14.29 %
