a)
Interpretation: The vapor pressure of solution along with mole fraction composition of Pentane in the vapor has to be calculated.
Concept Introduction: Raoult’s law for ideal solution states that the mole fraction of the solvent is directly proportional to the vapor pressure of an ideal solution. Raoult’s law can be expressed by the equation,
Where,

- A student wants to make the following product in good yield from a single transformation step, starting from benzene. Add any organic reagents the student is missing on the left-hand side of the arrow, and any addition reagents that are necessary above or below the arrow. If this product can't be made in good yield with a single transformation step, check the box below the drawing area. Note for advanced students: you may assume that an excess of benzene is used as part of the reaction conditions. : ☐ + I X This product can't be made in a single transformation step.arrow_forwardPredict the major products of this organic reaction:arrow_forwardCalculate the density of 21.12 g of an object that displaces 0.0250 L of water.arrow_forward
