Question

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

Answer 1

Answer:

Molarity of the NaOH solution = 2.5 M

Explanation:

Given:

Moles of naoH = 0.50 moles

Volume of water = 200.0 ml

To determine:

Molarity of the solution

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

$Molarity = \frac{moles\ of\ solute}{Volume (L)\ of \ solvent}\\ \\For\ NaOH\\\\Molarity = \frac{0.50\ moles}{0.200\ L} =2.5\ moles/L$

Answer 2

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
