Asked by Irma
In a mountainous location, the boiling point of pure water is found to be 95°C. How many grams of sodium chloride must be added to 9 kg of water to bring the boiling point back to 99°C? Assume that i = 2.
So what will my answer be in grams?

delta T =i*Kb*molality
Solve for molality. i = 2 for NaCl.
molality = moles/kg solvent.
Solve for moles.
moles = grams/molar mass.
