(Q68) What mass (in grams) of ethylene glycol (C2H,O2) must be added to 1,312 grams of water to
lower the freezing point to -1.70 °C? (3 sf)
1-Intermolecular forces of interaction influence the algebraic signs (“+” or “-“) and the magnitude of DHsoln. Consider a solution composed of liquid-A and liquid-B, such that the intermolecular force between molecules A and B is stronger than either between A and A or B and B.
(a) Does the formation of an A-B solution result in a positive DHsoln (implying an endothermic process) or a negative DHsoln (implying an exothermic process)? Explain your reasoning.
(b) If you have a solution that contains 50% of each by mole quantity, would the boiling point of the solution be higher or lower than the average boiling points of the individual liquids? Explain.
The partial pressure of O2 in your lungs varies from 25.0 mm Hg to 40.0 mm Hg.KH (O2 in water at 25.0⁰C) = 1.30 x 10-3 mol/kg.bar. Assume ρ (H2O) = 1.00 g/mLIf the partial pressure of O2 is 40.0 mm Hg, the mass of O2 (in mg) that can dissolve in 1.00 L water at 25⁰C would be
