Question

Calculate the molarity of a solution prepared by dissolving 9.8 moles of solid NaOH in enough water to make al 3.62 L of solution

Answer 1

The molarity of the solution is 2, 71 M.

Step-by-step explanation:

Molarity is a concentration measure that expresses the moles of solute (in this case NaOH) per liter of solution. We perform a simple rule of three calculation to obtain the molarity:

3,62 L solution------9,8 moles of NaOH

1 L solution ----------x= ( 1 L solution x 9,8 moles of NaOH)/3,62 L solution

x=2, 71 moles of NaOH ---> The solution is 2,71 M.
