The molar absorptivity of ascorbic acid is determined using a 0.50 mM (±0.04 mM) solution. The solution had an absorbance reading of 0.20±0.02 using a cell with a 1.00±0.01 cm. Calculate the uncertainty in the molar absorptivity of the ascorbic acid using propagation of errors and determine which measurement contributes the most to the error. Remember A = εbc
