Gravity on earth is 9.8 m/s2, and gravity on the moon is 1.6 m/s2.

so, if the mass of an object on earth is 40 kilograms, its mass on the moon is kilograms and its weight on the moon is newtons.

How many grams of co(g) are there in 74.5 ml of the gas at 0.933 atm and 30o c?

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 a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?
