Interpretation:
Theconcentration that does not change on heating a solution to 75°Cis to be identified.
Concept introduction:
The number of grams of solute present in
Percent by mass of a solution is obtained by dividing the mass of solute by the mass of solution (i.e., mass of solute and mass of solvent), which is then multiplied by
Mathematically, the percent by mass of a substance is written as
Molarity is the number of moles of solute that present in one litre of solution.
Mathematically, it can be expressed as follows:
Mole fraction is defined as the ratio of number of moles of given component to total number of moles of solution.
Mathematically mole fraction of component A can be expressed as follows:
Molality is defined as number of moles that present in one kilogram of the solvent.
Mathematically, it can be expressed as follows:
Moles of the solute and mass of the solvent are not affected by temperature.

- Which of the following solutes do you expect to be more soluble in water than in cyclohexane: a dimethyl ether, b hexane, c tetrachloroethene, d hydrogen fluoride? Explain your choices.arrow_forwardAntifreeze solutions are aqueous solutions of ethylene glycol, C2H6O2(d=1.12g/mL). In Connecticut, cars are winterized by filling radiators with an antifreeze solution that will protect the engine for temperatures as low as -20F. (a) What is the minimum molality of antifreeze solution required? (b) How many milliliters of ethylene glycol need to be added to 250 mL of water to prepare the solution called for in (a)?arrow_forwardBeaker A has 1.00 mol of chloroform, CHCl3, at 27C. Beaker B has 1.00 mol of carbon tetrachloride, CCl4, also at 27C. Equal masses of a nonvolatile, nonreactive solute are added to both beakers. In answering the questions below, the following data may be helpful. Write , =, or more information needed in the blanks provided. (a) Vapor pressure of solvent over beaker B vapor pressure of solvent over beaker A. (b) Boiling point of solution in beaker A boiling point of solution in beaker B. (c) Vapor pressure of pure CHCl3 vapor pressure of solvent over beaker A. (d) Vapor pressure lowering of solvent in beaker A vapor pressure lowering of solvent in beaker B. (e) Mole fraction of solute in beaker A mole fraction of solute in beaker B.arrow_forward
- Match the vapor pressure diagrams with the solute-solvent combinations and explain your answers. a. and b. and c. and d. andarrow_forwardAn aqueous solution of a molecular compound freezes at 0.086C. What is the molality of the solution?arrow_forwardA gaseous solute dissolves in water. The solution process has H=15 kJ. Its solubility at 22C and 6.00 atm is 0.0300 M. Would you expect the solubility to be greater or less at (a) 22C and 1 atm? (a) 18C and 6 atm? (a) 15C and 10 atm? (a) 35C and 3 atm?arrow_forward
- If a salt is added to water, which of the following is likely to occur? a.The boiling point will increase and the freezing point will decrease. b.The boiling point will increase and the freezing point will increase. c.The boiling point will decrease and the freezing point will decrease. d.The boiling point will decrease and the freezing point will increase.arrow_forwardYou have read that adding a solute to a solvent can both increase the boiling point and decrease the freezing point. A friend of yours explains it to you like this: The solute and solvent can be like salt in water. The salt gets in the way of freezing in that it blocks the water molecules from joining together. The salt acts like a strong bond holding the water molecules together so that it is harder to boil. What do you say to your friend?arrow_forward
