what is the molarity of a solution that contains 25.0 g of vitamin b, hydrochloride (with a molar mass of 337 g/mol) in 390 ml of solution?

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

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:

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
