Kimia Fisik dan Analisis Kelas 12 SMA. Larutan 2,5 gram BHT dalam 100 gram benzena membeku pada 4,88 oC.0 g of benzene.
What is the molar mass of eicosene if Kf for benzene is 4. 1. A nonvolatile, nonelectrolyte that dissolves in benzene is TNT (trinitrotoluene).% Cr were put through stability tests lasting 300 …
Redox & Coordination Kf; Spectroscopy; Solvent data (including Kf,Kb) Solubility data; Substituent constants; vapor pressure H2O; Molecular parameters; Character Tables; Links; Molal Freezing and Boiling Point Data. Rearranging the formula to solve for m, we get m = ΔTf / Kf = 18. Hitung titik bekunya! Jawaban: ΔTf = (gr zat terlarut / Mr) x (1000 / g pelarut) x Kf
The normal freezing point of benzene is 5.12 °C/m.53∘C to 4.
