Answer:

The answer is 8.29 %

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 = 19.30g/L

error = 20.9 - 19.3 = 1.6

We have


p(\%) = (1.6)/(19.3) * 100 \\ = 8.290155440...

We have the final answer as

8.29 %

Hope this helps you
