Example Question #1 : Laboratory Techniques And Analysis
The literature value for the melting point of a given compound is 240 degrees Celsius. A scientist uses the melting point apparatus to experimentally measure the compound's melting point at 230 degrees Celsius. What is the scientist's percent error?
The percent error is given by the following formula:
In this case, the theoretical value is 240 degrees Celsius, and the actual value is 230 degrees Celsius. The percent error is thus calculated to be 4.16 %. The calculation is as follows:
