Respuesta :
The molarity of the solution is 0.1442 M
Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per liters of the solution. Molarity is also known as the molar concentration of a solution.
In order to calculate the molarity of a solution, you need to know two things that is the number of moles of solute present in solution and along with that the total volume of the solution.
In the question given above to find the number of moles;
number of moles = Volume × Molarity
= 72.1 × 0.200 ⇒ 14.42 moles
Now to calculate the molarity we use;
M = Number of moles ⇒ 14.42 ⇒ 0.1442 M
Total volume 100
