Answer to Question #153739 in General Chemistry for Mico

Question

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 1

%error = (approximate value - exact value)/ exact value × 100%

=(2.69-2.68)/(2.68) × 100%

= 0.37%
