A solution is prepared by dissolving 0.222 2 (0.000 2) g of KIO3 [FM 214.001 0 (± 0.000 9)] in enough water to prepare a 50.00 mL of solution. The tolerance of the volumetric flask used to make the solution is 0.05 mL. a. What is the concentration of the solution (and the relative error of the concentration) in Molarity? b. A 5.00 (±0.01) mL aliquot of the solution is diluted in a 100.00 (±0.08) mL volumetric flask. What is the concentration of the diluted solution (and the absolute error of the concentration

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
