You were given a small block of aluminum and asked to calculate its density at room temperature. After performing the necessary measurements, you computed the density to be 2.69 g/cm3 but the true density of aluminum is 2.68 g/cm3. What is the percentage error of your measurement?

Answer»

%ERROR = (APPROXIMATE VALUE - EXACT value)/ exact value × 100%=(2.69-2.68)/(2.68) × 100%= 0.37%
