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 dog 10 2) cm O none of the above Question 2 The mass of the coloured compound in the same solution as in question 1 above that would 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 / log10 2 O 0.075 / log10 0.5 O none of the above
