A dual-wavelength spectrometer uses 780 nm and 830 nm. The molar extinction coefficients for oxy-hemoglobin (HbO_{2}) and deoxy-hemoglobin (Hb) at these two wavelengths are: e_HbO_{2}_780nm = 710 cm^{-1}M^{-1}, e_Hb_780nm = 1075 cm^{-1}M^{-1}, e_HbO_{2}_830nm = 974 cm^{-1}M^{-1}, e_Hb_830nm = 693 cm^{-1}M^{-1}. The spectrometer measures absorption coefficients at these two wavelengths are: m_{a}_780nm = 0.057 cm^{-1}, m_{a}_830nm = 0.063 cm^{-1}, please calculate the concentration for HbO_{2} and Hb (in unit of mM), as well as total hemoglobin concentration, and oxygen saturation.
