Solutions, colligative property conceptual doubt

The number of moles of acetic acid here are = 45
number of moles of H2O here are = 150

We use the Kf of water here to get the correct answer because water has more moles
But acetic acid is definitely not negligible here
Suppose we had 99 moles of acetic acid and 100 moles of water. Would we still use the exact Kf of water? why? if there were 101 moles of acetic acid and 100 moles of water, would we suddenly use the Kf of acetic acid? how does this work
