Asolution is made by dissolving 1.00 moles of sodium chloride (nacl) in 155 grams of water. if the molal boiling point constant for water (kb) is 0.51 °c/m, what would be the boiling point of this solution? show all of the work needed to solve this problem.

Molality = 1.00 mol/ 0.155 Kg = 6.45 
delta T = m x kb x i 
i = Vant'Hoff factor for NaCl = 2 

delta T = 6.45 x 0.51 x 2 = 6.6 
boiling point = 100 + 6.1 = 106.1 °C 

moles glucose = 15.5 g / 180 g/mol=0.0861 
m = 0.0861 mol/ 0.245 Kg =0.351 
delta T = 0.351 x 1.86 =0.65 
freezing point = - 0.65 °C
