Question

A student estimated the volume of a liquid in a beaker as 200.0 mL. When she poured the liquid into a graduated cylinder she MEASURED the volume to be 198.2 mL. What is the percent error?

Answer 1

The answer is 0.91 %

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 volume = 198.2 mL

error = 200 - 198.2 = 1.8

So we have

`P(\%) = (1.8)/(198.2) * 100 \\ = 0.90817356205...`

We have the final answer as

0.91 %

Hope this helps you
