NO * No, the value you entered for the concentration of the acetic acid is incorrect. The expression you should be evaluating is: MHC,H,o,(mmolmL-1) = MNaOH (Avg)(mmolmL−1) × VNaOH(mL) VHC₂H₂O, (ML) Where: • MNaOH (Avg) is the average molarity of NaOH VN₂OH is the volume of NaOH VÍC₂H₂O₂ is the volume of acetic acid SOLVE 1 mmol HC₂H3O2 1 mmol NaOH At least 6 significant figures should be retained to prevent accumulating rounding errors when the value is used in a subsequent calculation.
