Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
Answer:
im absoulutely positive it is C
Aloha~! My name is Zalgo and I am here to help you out today. Those sort of conditions could be fore-boding/foreshadowing/warning that there will soon be a storm or that it will rain quite a lot. In the case of it being a storm, you should be a small room where there are no windows and nothing that is small that will fly towards you that could kill you.
I hope that this helps! :D

In this question, what are we really being asked? We are being asked about the number of moles there in 2.0x10^22 molecules of H2O.
We are going to use the formula,
Number of moles = Number of molecules / Avogadro's number
We have the number of molecules: 2.0 x 10^22
Avogadro's number: 6.02 x 10^23
Now we will plug in our information in a scientific calculator:
(2.0 x 10^22) / (6.02 x 10^23) = 0.03 moles is our answer.
