what is the boiling point of a solution of nacl in water if the solution freezes at −0.93 °c

Question

what is the boiling point of a solution of nacl in water if the solution freezes at −0.93 °c

Answer 1

ΔT = imK

0.93 = (2)(m)(1.86)

Solve for m (molality) and use it in ΔT = imK where i = 2 and K = 0.512 and find ΔT. Add that value to 100^oC to find boiling point
