Freezing point depression is a colligative property. The more solute dissolved, the more the freezing point decreases,

#DeltaT_f = iK_fm#

#i= 1# for glucose, since it doesn't measurably dissolve into more than one molecule/ion.

#DeltaT_f = 1 * (1.86°C)/m * (27g * ("mol"C_6H_12O_6)/(180g))/(125g * (kg)/(10^3g)#
#therefore DeltaT_f approx 2.23°C#
