How many molecules are in 2.50 moles of h2o

Explanation:

According to the mole concept there are atoms or molecules are present in 1 mole of a substance.

Mathematically,    1 mole = atoms or molecules

Therefore, calculate the number of molecules present in 2.50 moles of as follows.

                  = molecules

Thus, we can conclude that there are molecules in 2.50 moles of .

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
