An industrial chemist is studying smAll organic compounds for their potential use as an auto antifreeze. When 0.243g of a compound is dissolved in 25.0 ml of water, the freezing point is -0.201 degree celcius.

Question

(A) Calculate the molar mass of compound (dH2O= 1.00g/ml) at temp of solution.

Answer 1

calculate molality first.

-.201=-1.86 m

then, molality= .243/(molmass*.025)
solve for mol mass.
