please help me answer question 1 to 3, thank you Chapter 9, Solutions, Review & Extra Credit. 2 Points for each XC correct answer; 6 points total, max. Partial Credit given. Suggestions...work in teams [it will improve the learning experience] 1. Solutions-A solution forms when a solute (the smaller quantity) dissolves in a solvent (the larger quantity). In a solution, the particles of solute are evenly distributed in the solvent. A solute may be a gas, liquid or solid. A...
Part 3. Problems 1) The molarity of naphthaline in a solution of naphthalene (CH. MW-128.8), a non-ionizing and nonvolatile solute, and benzene (C.HS, MW = 78.11), a volatile solvent, is [CHx] = 0.125 M. The density of the solution is D= 0.8781 g/cm! Find the following: a) The osmotic pressure exerted by the solution, at T = 25.0°C. Give your final answer in units of torr. [8 points] b) Xn, the mole fraction of naphthalene in the solution.
