Calculate the fre

We know

ΔT _f= k _f × m

Where ΔT_f is the depression in the freezing point

K_f freezing constant for water

m is molality

The molality(m) of a given solution of glucose:

M=1.33 mol kg^-1

Putting the values in the equation, we get

ΔT_f= 1.86 × 1.33K

ΔT _f= 2.4738K

ΔT _f = T _f × 2.4738K

Δt_{(solution) =} t_(solvent) – ΔT_f

ΔT _f= T_f⁰ 2.4738K

= 273.15 - 2.4738K

= 270.65K
