A solution of ethylene glycol in water at 20.0°C has a mass percent of 8.25% of ethylene glycol with a density of 1.0087 g/mL. The freezing point depression constant for water (which you can assume is the solvent for all solutions) is K1.86°C kg/mol and the boiling point elevation constant is Kb the following: 0.512°C kg/mol. The density of neat water at 20.0°C is 0.9982 g/ml. Answer 1. What is the molarity of the solution? 2. What is the molality...
In an ethylene glycol-water solution, there are 20.0 g ethylene glycol for every 80.0 g water. This solution is used for filling a 450.0 gallon reservoir. Suppose the density of this mixture solution is ρ= 1.0529 g/ml. (a) What is the molarity of this solution? (b) If you need to fill the 450.0 gallon tank in 170.0 s, what is the volumetric flow rate of the solution into the tank? (c) How many moles of ethylene glycol are in the...
When water is added to ethylene glycol, the viscosity of the solution decreases when compared to pure ethylene glycol. Which of the following is the BEST explanation of why this occurs? Ethylene glycol is thick and water is thin, so when mixed together it makes a medium thick solution The water molecules increase the intermolecular interactions between the ethylene glycol molecules, which allow them interact with other molecules, the resulting solution less viscous. The water molecules increase the intermolecular interactions...
