Question

The molarity of a solution that contains 0.50 moles of naoh in 200.0 milliliters of water is

Answer 1

200.0 mL =0.2000 L
Molarity = number of mole solute / volume solution(L) = 0.50 mol/0.2000 L=
= 2.5 mol/L =2.5M

Answer : 2.5 M

Answer 2

Molarity of the NaOH solution = 2.5 M

Step-by-step explanation:

Given:

Moles of naoH = 0.50 moles

Volume of water = 200.0 ml

To determine:

Molarity of the solution

Step-by-step explanation:

Concentration of a given solution is expressed in terms of molarity which is the ratio of the moles of solute present per liter of the solvent

`Molarity = (moles\ of\ solute)/(Volume (L)\ of \ solvent)\\ \\For\ NaOH\\\\Molarity = (0.50\ moles)/(0.200\ L) =2.5\ moles/L`
