A solution is made by dissolving 3.60 g of sodium chloride in water to
a final volume of 115 mL solution.
What is the weight/weight % or
percent by mass of the solute?
Use 1.00 g/mL for the density of the solution.

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

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.
