What is the volume of a 2 M NaOH solution needed to obtain 4 moles of NaOH? (2021) 2021

Step 1: Understand that molarity (M) is the number of moles of solute per liter of solution.
Step 2: Identify the given values: you have 4 moles of NaOH and a solution with a molarity of 2 M.
Step 3: Use the formula for volume: Volume (L) = moles / molarity.
Step 4: Plug in the values: Volume (L) = 4 moles / 2 M.
Step 5: Calculate the volume: 4 moles divided by 2 M equals 2 L.
Step 6: Conclude that you need 2 liters of the 2 M NaOH solution to obtain 4 moles of NaOH.
