Question

pose you work for a gas production company. One of the things you have to be extremely cerned about is the volatility of the liquid fuels you are working with throughout the day. Which of the following compounds would result in lowering the volatility of the fuel the most and why? HC_2H_3O_2 Mg(NO_3)_2 LiCl Fe Suppose you add 25.0 grams of C_6H_12O_6 to 100.0 mL of C_8H_18 (d_C8H18 = 0.699 g/mL) which has an original vapor pressure of 0.014 atm. What is the vapor pressure of the solution? Vapor pressure lowering of a solvent by the addition of a solute is a _______ property Suppose you add CH_3OH (d = 0.791 g/mL) to C_8H_18 (d = 0.699 g/mL) in order to reduce the volatility of C_8H_18. Will the vapor pressure be lowered? Explain your answer.

Explanation / Answer

iii) Coligative properties are properties of solutions that depend on the ratio of the number of solute particles to the number of solvent particles in the solution and not on the nature of the chemical species present. These properties are mostly studied for dilute solutions, whose behaviour may often be approximated as that of an ideal solution.
