Question: The spreadsheet gives the product b for four pure compounds and a mixture at infrared wavelengths. Modify Figure 18-5 to solve four equations and find

The spreadsheet gives the product b for four pure compounds and a mixture at infrared wavelengths. Modify Figure 18-5 to solve four equations and find the concentration of each compound. You can treat the coefficient matrix as if it were molar absorptivity because the pathlength was constant (but unknown) for all easurements.
