The absolute uncertainty (au) can be taken as the minimum measure an instrument can provide whereas the relative uncertainty (ru) is the percent of the magnitude of the measure (m) the absolute uncertainty represents. ru = (ua/m) times 100 Calculate the relative uncertainty in a volume of 25.00 mL that was measured with an instrument with an instrument with an absolute uncertainty of 0.05 mL. That is 25.00 plusminus 0.05 mL. When two or more measurements are added or subtracted, the absolute uncertainty of the result is the sum of the individual absolute uncertainties. When the numbers are multiply or divided, the relative uncertainty of the result is the sum of the individual relative uncertainties. Calculate the total volume and its absolute uncertainty when mixing 35.50 plusminus 0.05 mL and 23.50 plusminus 0.01 mL of a solution.
