Question

6. An object has a mass of 36.0 grams. On Anthony's balance, it weighs 34.85 grams. What is the percent error of his balance?
7. Shelby measured the volume of a cylinder and determined it to be 54.5 cm³. The teacher told her that the volume should have been 55.7cm³. What is her percent error?
8. Walter found the mass of an object to be 100.7 grams. His textbook listed the mass to be 102.7 grams. What is his percent error?
9. After lab, all of Darrel’s friends looked at his data and laughed and laughed. They told him that he was 30.8% too low in the boiling point he had just recorded. He had recorded a boiling point of 50° C on his data sheet. What is the correct boiling point of the liquid he was working with in lab?

The percent error is calculated using the formula: Percent Error = |(Experimental Value - True Value) / True Value| × 100%. For Anthony's balance:
Percent Error = |(34.85 - 36.0) / 36.0| × 100% = 3.19%
The percent error is calculated using the formula: Percent Error = |(Experimental Value - True Value) / True Value| × 100%. For Shelby's measurement:
Percent Error = |(54.5 - 55.7) / 55.7| × 100% = 2.15%
The percent error is calculated using the formula: Percent Error = |(Experimental Value - True Value) / True Value| × 100%. For Walter's measurement:
Percent Error = |(100.7 - 102.7) / 102.7| × 100% = 1.95%
To find the correct boiling point, use the formula: Correct Value = Recorded Value / (1 - Percent Error). For Darrel's measurement:
Correct Boiling Point = 50 / (1 - 0.308) = 72.25°C
