The molar mass and vapor pressure of solution of sodium diatrizoatein pure water needs to be determined, if the vapor pressure of pure water at 31.2°C is 34.1 torr. Concept Introduction: When a non-volatile solute is dissolved in solvent to get solution, the vapor pressure decreases for the solution and it can be calculated with the help of Raoult’s law that states that the vapor pressure of solution is the product of mole fraction of solvent and vapor pressure of pure solvent. When a volatile solute is added to the solvent, the overall vapor pressure of solution will be the sum of vapor pressure contribution of individual component. The mathematical expression can be written as: P solution = [χ A × P A ] + [χ B × P B ]

What are the angles a and b in the actual molecule of which this is a Lewis structure? H- :0: C=N: b Note for advanced students: give the ideal angles, and don't worry about small differences from the ideal that might be caused by the fact that different electron groups may have slightly different sizes. a = 0° b=0 X

A student proposes the transformation below in one step of an organic synthesis. There may be one or more products missing from the right-hand side, but there are no reagents missing from the left-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. • If the student's transformation is possible, then complete the reaction by adding any missing products to the right-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + This transformation can't be done in one step.
