For the below reaction, which O would most likely be attack first?  Which of the alcohols would be the main one made? 1,3-propandiol or propylene glycol?

Your products will be glycerol (the triol, no diols) and acetone.

Thanks!  So what is basically happening is that the H+ is attacking the O on the left side (as drawn) and through several steps the molecule is broken, the left O is used for the acetone and an OH is added to the other fragment which regenerates the catalyst?

Those are the correct products. Make sure you look up the mechanism, this is acetal hydrolysis.
