1.) How many moles of ions are released when 0.27 moles of CoCl2 is dissolved in water?

The Cl would be broken down by the water so do measure out the percentage of Cl that is present and use the amount of Cl to determine the moles of ions?


Also,

2.) A 5.54-g sample of vinegar was neutralized by 30.10 mL of 0.100M NaOh. What is the precent (by weight) of acetic acid in the vinegar?
(Acetic acid is CH3COOH)

As for this question, I'm confused by the fact that the vinegar is in grams. Shouldnt the sample of vinegar be of a liquid measurement? I don't really know, I'm horrible at titration.

Any help would be appreciated.

Show your attempt.
1. hint - assume  a complete dissociation in water solution (not exactly correct)

2. Start from a balanced reaction

You are asked to give weight percentage, that means you need to calculate mass of acetic acid in the sample.
