Question: If 0.5 moles of NaCl are dissolved in 1 liter of water, what is the concentration of NaCl?

Options:

  1. 0.5 M
  2. 1 M
  3. 2 M
  4. 0.25 M

Correct Answer: 0.5 M

Solution: 

Concentration (M) = moles of solute / liters of solution = 0.5 moles / 1 L = 0.5 M.

Questions & Step-by-Step Solutions

If 0.5 moles of NaCl are dissolved in 1 liter of water, what is the concentration of NaCl?
  • Step 1: Identify the amount of NaCl (sodium chloride) you have, which is 0.5 moles.
  • Step 2: Identify the volume of water (solution) you are using, which is 1 liter.
  • Step 3: Use the formula for concentration, which is Concentration (M) = moles of solute / liters of solution.
  • Step 4: Plug in the values: Concentration (M) = 0.5 moles / 1 L.
  • Step 5: Calculate the concentration: 0.5 moles divided by 1 liter equals 0.5 M.
  • Molarity – Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.
