What is the molarity of a sodium hydroxide solution if 0.4 moles are dissolved in 2 liters of water?

What is the molarity of a sodium hydroxide solution if 0.4 moles are dissolved in 2 liters of water?

Step 1: Identify the number of moles of sodium hydroxide (NaOH) you have. In this case, it is 0.4 moles.
Step 2: Identify the volume of the solution in liters. Here, it is 2 liters.
Step 3: Use the formula for molarity, which is Molarity (M) = moles of solute / liters of solution.
Step 4: Plug in the values into the formula: M = 0.4 moles / 2 liters.
Step 5: Calculate the result: 0.4 divided by 2 equals 0.2.
Step 6: State the final answer: The molarity of the sodium hydroxide solution is 0.2 M.
