What is the mass of a sample of water that takes 2000 kj of energy to boil into steam at 373 k. the latent heat of vaporization of water is 2.25 x 10^6 j kg-1.

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.

What is the molar mass of a gas that has density of 2.054 g/l
