The molar mass dependence of the concentration dependent part of D c was also calculated from the zero concentration extrapolated values with the corresponding effective hydrodynamic radii. For the calculations the Pyun-Fixman theory was applied which regards the polymer coils as soft, interpenetrable ...
To solve the problem, we need to calculate the mass of a compound that will lower the freezing point of benzene by 0.48 K. We will use the formula for depression of freezing point, which is given by: ΔTf=Kf⋅m Where:- ΔTf = depression in freezing point (0.48 K)- Kf = cryosco...
To solve the problem of determining the mass of NaCl that must be dissolved in 65 g of water to lower the freezing point by 7.5°C, we can follow these steps:Step 1: Understand the Freezing Point Depression Formula The formula
