How To Calculate Freezing Point Of A Blend Of Two Mixtures With Known Freezing Points,compositions Mathematically?

[dedoooo]

Suppose I Have Two Hydrocarbon Mixtures ,Each Mixture Has Known Composition & Freezing Point , Is There Any Empirical Formula To Calculate The Freezing Point Of a Blend Of Those Mixtures?

I assume you have to put the freezing points into degrees Kelvin.
Maybe you just then calculate it based on the relative proportions (not sure if based on mass, volumes, moles or what)

[ChuckFickens]

ΔT=km

k is the freezing point depression of the solvent (the larger part of the mixtures)
m is the molality of the solution

Δ just means the difference, so once you've done KM subtract ΔT from the freezing point of the solvent.
