Please calculate the concentrations of Tartrazine (TZ) and Allura Red (AR) in the unknown mixture using the coresponding data. Solve by using 2x2 simultaneous linear equation.
Slope of TZ at 430 nm = y=0.024x
Slope of AR at 430 nm = y=0.0073x
Slope of TZ at 480 nm = y=0.0075x
Slope of AR at 480 nm = y=0.0183
Absorbance of the unknown mixture at 430 nm = 0.791
Absorbance of the unknown mixture at 480 nm = 0.383
Undiluted molarity of TZ = 42.1
Undiluted molarity of AR = 21.2
