Question

researcher measures the mass of a sample to be 5.51 g. The actual mass of the sample is known to be 5.80g. Calculate the percent error.

Answer 1

5% is the percent error

Step-by-step explanation:

Percent error is defined as the 100 times the ratio of absolute value of the difference between the measurement and the theoretical value and the theoretical value, that is:

`(|Theoretical-Measurement|)/(Theoretical) * 100`

In the problem, theoretical value is 5.80g and the measurement is 5.51g:

`(|5.80g-5.51g|)/(5.80g) * 100`

% =

5% is the percent error
