The absorbance of sample A is higher than the absorbance of sample B.    Therefore, sample A has (circle the correct one)   more   /   less      dissolved solute than sample B. The absorbance is (circle the correct one)   directly    /    inversely      related to the transmittance of a sample.

Which absorbance spectrum from the previous problem represents the dye solution with the greatest concentration? 1.4 1.2 Curve 3 0.8 0.6 Curve 2 Curve 1 0.4 0.2 0.2 Wavelength (nm) O All three are approximately the same concentration O Curve 3 O Cannot be determined from the information given Curve 2 Curve 1 700 580 Absorbance
