`x` mole of `KCl` and `y` mole of `BaCl_(2)` are both dissolved in `1kg` of water. Given that `x+y=0.1` and `K_(f)` for water is `1.85K//"molal`, what is the observed range of `DeltaT_(f,)` if the ratio of `x` to `y` is varied ?

Options

A. `0.37^(0)` to `0.555^(0)`
B. `0.185^(0)` to `0.93^(0)`
C. `0.56^(0)` to `0.93^(0)`
D. `0.37^(0)` to `093^(0)`

Answer

A
