Question

The Handbook of Chemistry and Physics lists the density of a certain liquid to be 0.7988 g/mL. Taylor experimentally finds this liquid to have a density of 0.7925 g/mL. What is his percent error?

Answer 1

The answer is 0.79%

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 = 0.7988 g/mL

error = 0.7988 - 0.7925 = 0.0063

So we have

`P(\%) = (0.0063)/(0.7988) * 100 \\ = 0.788683024...`

We have the final answer as

0.79 %
