What is the freezing point of a solution that contains 36.0 g of glucose in 500.0 g of water (kf for water is 1.86c/m. the molar mass of glucose is 180.0 g per mole.)
a 0.755
b -0.744
c 1.49
d-1.49

what is the molality of a solution of water and kcl if the boiling point of the solution is 103.07 degrees celcius. (kb for water =0.512 c/m, kcl is an ionic compound)
a 0.300
b 0.600
c 3.00
d 6.00

! i have been having so much trouble with this. have no idea where to even start!
