When you calculate results that are aiming for known values,
the percent error formula
is useful tool for determining the precision of your calculations. The formula
is given by: The experimental value is your calculated value, and the
theoretical value is your known value.
% error = | ( experimental – theoretical) / theoretical | *
100
% error = | (44 – 45.5) /45.5| * 100
% error = 3.30 %
