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=numberofreactioneventsnumberofphotonsabsorbed . Suppose a quantum yield for the reaction CH3X→CH3+Xis ϕ= 0.95. A cuvette containing a solution of CH3Xis irradiated with 280-nmwith a power of 885 mWfor 10.0 minutes. Part A Assuming total absorption of the light by the sample, what is the maximum amount (in moles) of CH3Xthat breaks apart?Express your answer to two significant figures. nothingmolCH3Xm o l C H 3 X actual

An acceleration voltage of 15.0 kV is used to accelerate ions into the 1.48 m flight tube of a time-of-flight (TOF) mass spectrometer. The frequency at which spectra can be recorded is dependent on how long it takes the slowest ion to travel from the source to the detector. If you wish to scan up to m/z 13039, at what frequency (spectra/s) could spectra be recorded if a new spectrum begins each time the slowest ion reaches the detector? frequency: spectra/s
