Which of the following operations yields the number of moles of solute?
a. molarity x liters of solution
b. molarity x moles of solution
c. molarity x mass of solution
d. moles of solution /volume ofsolution?

Answer : The correct option is, (a) molarity × liters of solution

Explanation :

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used for molarity is :

or,

Thus, the correct option is, (a) molarity × liters of solution

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:

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
