Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at −14.5 ∘c? the freezing point for pure water is 0.0 ∘c and kf is equal to 1.86 ∘c/m. express your answer to three significant figures and include the appropriate units.

When water dissociates, each water molecule splits into a hydroxide ion and a) h 3 o + b) a hydrogen atom c) a hydrogen ion d) h 2 o e) oh —
