Problem

The quantum yield of light-induced chemical reactions (called photochemical reactions) measures the efficiency of the process. The quantum yield, φ, is defined as: φ = (number of reaction events)/(number of photons involved). Suppose a quantum yield for the reaction CH3X → CH3 + X is φ = 0.56. A cuvette containing a solution of CH3X is irradiated with 280-nm light with a power of 885 mW for 10.0 minutes. Assuming total absorption of the light by the sample, what is the maximum amount (in moles) of CH3X that breaks apart?
