The literature value of the atomic mass of an isotope of nickel is 57.9 g/mol. if a laboratory experimenter determined the mass to be 59.6 g/mol, what is the percent error?

17%

Explanation:

Given parameters:

Atomic mass of nickel isotope = 57.9g/mol

Experimental value of atomic mass = 59.6g/mol

Unknown:

Percentage error in the measurement.

Solution:

The percentage error shows how much uncertainty was introduced into a measurement. To calculate this, we simply use the expression below:

Percentage error =

Percentage error =  x 100 = 17%
