Answer:
1 molal aqueous solution of a nonionizing solute has a FP of −1.86∘C−1.86∘C.
a 0.1 molal..FP of -0.186
however HCl and CuSO4CuSO4 separate into 2 ions so those solutions have a
FP=2×−0.186FP=2×−0.186.
and K2SO4K2SO4 breaks up into 3 ions so
FP=3×−0.186FP=3×−0.186
the ratio is 2 : 2 : 3
The ratio is 1: 1: 1.5
