2 points 14. Denzel is calculating the average atomic masss of various elements.
Denzel calculated a mass of 32.75 g for the element phosphorus, which
has an accepted mass value of 30.97 g. What is the percent error of
Denzel's measurement?

The percent error of Denzel's measurement : 5.75%

Given

32.75 g measurement

Required

The percent error

Solution

% Error : difference between the theoretical value and the actual value

% Error for Denzel measurement :

1. Subtract the measurement value with the accepted value

= 32.75 g - 30.97 g

= 1.78 g

2. Divide by the accepted value, and multiply by 100

= (1.78/30.97) x 100%

= 5.75%
