(a) Interpretation: Whether the rate of dissolving if the solution is one-third saturated is more than, equal to, or less than the rate of dissolving when the solution is two-thirds saturated or not is to be stated. Concept introduction: Solution is a homogenous mixture of two or more components. A sample taken from any part of the solution will have the same composition as the rest of the solution. Many chemical reactions occur in water solutions.

Question

2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.
