0.02 M
10.6 M
0.1 M
Od 2.65 M
Question 3 (1 point)

The molarity of the given solution is 0.1 M.

Explanation:

We have to find the molarity of calcium chloride by converting the mass of CaCl₂ into its moles and dividing it by its volume in Litres.

We have to find the moles by dividing the mass of the substance by its molar mass.

Moles of CaCl₂ =

                       =

                       = 0.05 moles

Molarity =

             =  

              = 0.1 M

So the molarity of the given solution is 0.1 M.

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.
