Astudent uses visible spectrophotometry to determine the concentration of cocl2(aq) in a sample solution. first the student prepares a set of cocl2(aq) solutions of known concentration. then the student uses a spectrophotometer to determine the absorbance of each of the standard solutions at a wavelength of 510nm and constructs a standard curve. finally, the student determines the absorbance of the sample of unknown concentration. a wavelength of 510nm corresponds to an approximate frequency of 6×1014s−1. what is the approximate energy of one photon of this light? 9×1047j.
