WebSo London dispersion forces are proportional to how polarizable a molecule is, which is proportional to how large its electron cloud is, which is proportional to its molar mass. … WebThe average kinetic energy for a mole of particles, KE avg, is then equal to: KE avg = 1 2 M u rms 2. where M is the molar mass expressed in units of kg/mol. The KE avg of a mole of gas molecules is also directly proportional to the temperature of the gas and may be described by the equation: KE avg = 3 2 R T.
WebThe solubility of CaF 2 (molar mass 78.1) at 18°C is reported to be 1.6 mg per 100 mL of water. Calculate the value of Ks under these conditions.
