Solve for the measured or observed value.Note due to the absolute value in the actual equation (above) there are two solutions. For example, if 10 mL of liquid has a mass of 14 grams, then the density of the liquid is 1.4 grams per milliliter (14 g / 10 mL = 1.4 Wird verarbeitet... Divide the difference by the accepted value for the density and multiply the quotient by 100 [(measured density -- accepted density) ÷ accepted density x 100 = percent error].
