Answer:
Percent error = 5.44%
Explanation:
Percent error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 87
Theoretical value = 92
Substituting into the equation, we have;
[tex] Percent \; error = \frac {87 - 92 }{ 92} *100[/tex]
The negative value is ignored because we're trying to get the error.
[tex] Percent \; error = \frac {5 }{ 92} *100[/tex]
[tex] Percent \; error = 0.0544 *100[/tex]
Percent error = 5.44%
