Webb3 feb. 2024 · molality of ethylene glycol = ( 4.87 mol 698 gH2O)(1000 g 1 kg) = 6.98m From Equation 13.8.2, the increase in boiling point is therefore ΔTb = mKb = (6.98m)(0.51°C / m) = 3.6°C The boiling point of the solution is thus predicted to be 104°C. Webb14 juli 2024 · Calculate the number of moles of solute in the solution by multiplying the molality calculated in Step 3 by the given number of kilograms of solvent. Divide the given mass of solute by the number of moles calculated in Step 4. This is your molecular mass, or number of grams per mole, from which you can often guess the identity of the …
