29. (5 points) if you have 2.2 x 10^24 molecules of o2 at stp, how many liters of o2 do you have? show all work for credit.

One mole of a gas occupies 22.4L at STP. 
 Then it follows that 2.2 * 10^(24) molecules of O2 occupies X.  
 So X = (22.4 * 10^(24) * 22.4)/ 1 = 1.32911 * 10^(14)L 
 So basically, there's 132.911 * 10^(12) L of O2.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
