For a polyurethane sample in which carbon, nitrogen, and oxygen were detected by XPS, the sensitivity factor for C was 0.25 on the spectrometer used. The sensitivity factor for N was 0.42 and that for O was 0.66 on the same spectrometer. If the peak areas were C(1s) 5 26,550, N(1s) 5 4475, and O(1s) 5 13,222, what were the atomic concentrations of the three elements
