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%
