Question

A student identified the volume of a solution to be 13 milliliters. The true volume was 12.5 milliliters. What is the percent error of the measurement?

Answer 1

4 %

Step-by-step explanation:

The per cent error is given by

error = ( observed value - true value ) / true value x 100%

Now in our case

observed value = 13 mm

true value = 12.5 mm

therefore,

`\text{error}=(13-12.5)/(12.5)*100\%`
`error=(0.5)/(12.5)*100\%`

which simplfies to give

`error=0.04*100\%`
