Question: How many liters of a 0.5 M NaOH solution are needed to obtain 1 mole of NaOH? (2023)

Options:

Correct Answer: 1 L

Solution:

Volume = moles / molarity = 1 mole / 0.5 M = 2 L.

How many liters of a 0.5 M NaOH solution are needed to obtain 1 mole of NaOH? (2023)

How many liters of a 0.5 M NaOH solution are needed to obtain 1 mole of NaOH? (2023)

Step 1: Understand that molarity (M) is the number of moles of solute per liter of solution.
Step 2: Identify that you need to find the volume of a 0.5 M NaOH solution that contains 1 mole of NaOH.
Step 3: Use the formula for volume: Volume = moles / molarity.
Step 4: Substitute the values into the formula: Volume = 1 mole / 0.5 M.
Step 5: Calculate the volume: 1 mole divided by 0.5 M equals 2 liters.
Step 6: Conclude that you need 2 liters of the 0.5 M NaOH solution to obtain 1 mole of NaOH.

Molarity – Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.
Volume Calculation – The volume of a solution can be calculated using the formula: Volume = moles / molarity.
