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

Answer:

5% is the percent error

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:

$\frac{|Theoretical-Measurement|}{Theoretical} * 100$

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

$\frac{|5.80g-5.51g|}{5.80g} * 100$

% =

5% is the percent error
