Q1.
Moles of NaOH= 0.225 *60.75 /1000
=0.0137 MOLES
Mole ratio= 1:1
Molarity of acetic acid= 0.0137*1000/ 34.80
=0.393M

Q2.
ΔTf=i⋅Kf⋅b , where

ΔTf - the freezing-point depression;
i - the van't Hoff factor
Kf - the cryoscopy constant of the solvent;
b - the molality of the solution
3.95= i* 1.86*molarity
I=2
3.95= 2*1.86 * molarity
