The quantum yield for CO production in the photolysis of gaseous acetone is unity for wavelengths between 250 and 320 nanometers. After 20 minutes of irradiation at 313 nm, 18.4 cm cubed of CO (measured at 1008 pascals and 22 oC ) is produced. calculate the number of photons absorbed, and the intensity in J s-1.
