How many moles are in 2.35 x 10^25 molecules of copper?

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.

explanation:

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
