you make a solution by dissolving 25.0g of sodium chloride in 100.0 mL of water. What is the boiling point of the solution?

1 answer

mols NaCl = grams/molar mass
Solve for mols.

molality NaCl = mols NaCl/kg solvent
Solve for m.

delta T = i*Kb*m
i = 2 for NaCl. Solve for delta T, then add to 100 to find the new boiling point.
