0.984m x 0.6159kg = 0.0.606moles x 58.45g/mole = 35.......
How many grams (g) of sodium chloride should be dissolved in 615.9 g water to produce a solution that boils at 1.008 ºC above the boiling point of water? Kb= 0.512 ºC/molal. Use the ideal van't Hoff factor.

van't hoff factor for NaCl = 2
deltaT = i x Kb x m
1.008 = 2 x 0.512ºC/m x m
0.984m

0.984m x 0.6159kg = 0.606moles
0.606moles x 58.45g/mole = 35.44g NaCl
