Problem
A student transfers 2.00 mL (±0.02 mL) of a stock solution into a 100.0 mL volumetric flask and dilutes to the mark. The diluted solution has an absorbance of 0.225 in a 1.00 cm cuvette at a wavelength where the molar absorptivity is 5.00×103Lmol−1cm−1. Calculate the maximum possible percent error in the calculated concentration of the stock solution arising solely from the pipetting uncertainty.
