Question

Measuring the enthalpy of fusion of water, calculate the percent error in your determination of the value for the molar heat of fusion of ice.

Answer 1

Percent Error Definition

Percent error, sometimes referred to as percentage error, is an expression of the difference between a measured value and the known or accepted value. It is often used in science to report the difference between experimental values and expected values.

The formula for calculating percent error is:

Answer 2

The molar enthalpy of fusion for ice at 0 °C has an accepted value of +6.01 kJ/mol. Calculate a percent error value to compare your experimental result with the accepted value.
