Asolution of household vinegar is to be analyzed. a pipet is used to measure out 10 ml of the vinegar which is placed in a 250ml volumetric flask. distilled water is added until the total volume of solution is 250 ml portion of the diluted solution is measured out with a pipet and titrated with a standard solution of sodium hydroxide. the neutralization reaction is as follows: hc2h3o2 (aq) + oh- (aq) --> c2h3o2- (aq) + h2o (l)it is found that 16.7 ml of 0.0500 m naoh is needed to titrate 25.0 ml of the diluted vinegar. calculate the molarity of the diluted vinegar.
