Question: What volume of 0.5 M NaOH solution contains 1 mole of NaOH?

Options:

Correct Answer: 1 L

Solution:

Using the formula Molarity (M) = moles/volume (L), we rearrange to find volume = moles/Molarity. Thus, volume = 1 mole / 0.5 M = 2 L.

What volume of 0.5 M NaOH solution contains 1 mole of NaOH?

What volume of 0.5 M NaOH solution contains 1 mole of NaOH?

Step 1: Understand that Molarity (M) is a way to express the concentration of a solution, defined as moles of solute per liter of solution.
Step 2: Identify the given values: we have 0.5 M NaOH solution and we need to find the volume that contains 1 mole of NaOH.
Step 3: Use the formula for Molarity: M = moles / volume (L).
Step 4: Rearrange the formula to solve for volume: volume = moles / Molarity.
Step 5: Substitute the known values into the rearranged formula: volume = 1 mole / 0.5 M.
Step 6: Calculate the volume: 1 mole divided by 0.5 M equals 2 liters.
