Calculate the freezing point depression and molality for the benzoic acid solution and the freezing point depression constant for dodecanoic acid Kf, including uncertainty.
data:
molar mass (Dodecanoic acid)=200.32g/mol
molar mass (benzoic acid)=122.12g/mol
mass (benzoic acid)=0.9988g
mass(Dodecanoic acid)=7.2969g
Freezing temperature Tf of dodecanoic acid=43.550C
Freezing temperature Tf of the mixture of dodecanoic acid and benzoic acid solution=38.339C
