Can anyone explain how to solve this?

Suppose you conduct a laboratory experiment to measure the boiling point of methanol and your measurements showed the boiling point of methanol to be 62.4oC. However, the actual boiling point of methanol, which can be looked up in reference tables, is 64.9oC. What is the percent error of your measurement?

A. 0.80%

B. 1.08%

C. 3.85%

D. 4.01%

E. 7.50%
