What is 5.06 grams of oxygen in 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.

If 3 moles of a compound use 24 j of energy in a reaction, what is the a hreaction in j/mol?
