Calculate the moles of acetic acid in the vinegar taking into account that 22.42 mL of 0.356 M NaOH were added to completely neutralize 11.6 mL of the vinegar.
Homework Answers
in order to calculate the
number of moles of acetic acid , we have to consider the following
relation
1ml of 1M NaOH = 60.052g of acetic acid
this relation comes from the one is to one equivalence reaction of sodium hydroxide and acetic acid
thus by substituting the given values the number of moles of acetic acid is found to be 7.981 moles
