Webneeded to raise the boiling point of 43.5 g of benzene by 2.10 co? Kb for benzene is 2.67 cum. 6. 8. 9. If the boiling point of 69.6 g of carbon tetrachloride must be raised by 10.2 co, how many grams of pyridine (C H5N) must be dissolved in the carbon tetrachloride? Kb for carbon tetrachloride is 5.02 CO/ m. What is the boiling point elevation ... WebAug 23, 2024 · A mathematical equation is used to calculate the boiling point elevation or the freezing point depression. The boiling point elevation is the amount that the boiling point temperature increases compared to the original solvent. For example, the boiling point of pure water at \(1.0 \: \text{atm}\) is \(100^\text{o} \text{C}\) while the boiling ... WebJul 14, 2024 · First subtract the boiling point of water from this new boiling point: Then plug this value and a Kb of 0.512 into the equation for boiling point elevation and solve for molality: Next, take this molality value and multiply it by the given mass of the solvent, water, in kilograms: Last, divide the number of grams of the mystery solute by the ... scripts wholesale inc
