Spectroanalytical Methods

Spectroanalytical methods measure the wavelength and intensity of radiations that are either emitted or absorbed by a molecular or atomic species. These methods are useful for evaluating the electronic or atomic arrangement of the molecules of a given analyte.

Question

100 ml of a solution contains 0.050 g of a coloured compound that absorbs exactly half the
incident light intensity at 500 nm when the solution is in a 1.00 cm wide spectrophotometer
cell. The cell width that would absorb 75% of the incident light intensity is:
O 0.5 cm
O 1.0 cm
O 2.0 cm
O 4.0 cm
O log 10 2) cm
O none of the above
Question 2

have an absorbance of 1.5 in the same 1.00 cm cell is (in grams):
0.050
O 0.75 log10 2
O 0.033 log10 2
O 0.075 / log102
O 0.075 / log10 0.5
O none of the above
