What is the molarity of a solution that contains 0.500 mole of kno3 dissolved in 0.500-liter of solution?

Answer : The molarity of solution is, 1.00 M

Explanation : Given,

Moles of = 0.500 mol

Volume of solution = 0.500 L

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

Formula used :

Now put all the given values in this formula, we get:

Therefore, the molarity of solution is, 1.00 M

The correct answer is C. Electrostatic repulsion between the positively charged nucleus and alpha particles. Alpha particles contain positive charges. From the principle of like charge repels like charge, these positively charged alpha particles repelled or failed to collide with the positively charged nucleus; so they bounced back from each other.
