A 50 mL of a water sample is measured using a 100-mL class B graduated cylinder. The sample is analyzed using 0.000100 0.00005 M EDTA titrant and it is found that 9.10 mL are consumed to reach the equivalence point. The titrant is delivered from a 25-mL Class A burette starting at a volume of 1.00 mL and ending at 10.10 mL. Report the hardness uncertainty for this sample. Read the glassware tolerances from the Manual. Report all variables with the correct number of significant figures
