Answer:

Percent error = 4.29%

Step-by-step 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;

$Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100$

Given the following data;

Experimental value = 67

Theoretical value = 70

Substituting into the equation, we have;

$Percent \; error = \frac {67 - 70 }{ 70} *100$

$Percent \; error = \frac {3}{70} *100$

$Percent \; error = 0.04286 *100$

Percent error = 4.29%
