Ответ:
The percent error of Denzel's measurement : 5.75%
Further explanationGiven
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%
