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?

Respuesta :

Answer:

4 %

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,

[tex]\text{error}=\frac{13-12.5}{12.5}\times100\%[/tex][tex]error=\frac{0.5}{12.5}\times100\%[/tex]

which simplfies to give

[tex]error=0.04\times100\%[/tex][tex]undefined[/tex]
