The vapor pressure of water at 95C is normally 6.33.9 but decreased to 561.2mmHg upon addition of an unknown amount of NaOCl to 164.3g of water at this temp. How many grams of NaOCl was added assuming complete dissociation of the solute
delta P solvent = Xsolute*Posolvent
Then Xsolute = (moles solute)/(moles solute+moles solvent) and solve for g solute.Post your work if you get stuck.
