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

Options:

Correct Answer: 0.5 M

Solution:

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

If 0.5 moles of NaCl are dissolved in 1 liter of water, what is the molarity of the solution?

If 0.5 moles of NaCl are dissolved in 1 liter of water, what is the molarity of the solution?

Correct Answer: 0.5 M

Step 1: Identify the number of moles of the solute (NaCl) you have. In this case, it is 0.5 moles.
Step 2: Identify the volume of the solution in liters. Here, it is 1 liter of water.
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 = 0.5 moles / 1 L.
Step 5: Calculate the result: 0.5 moles / 1 L = 0.5 M.
Step 6: Conclude that the molarity of the solution is 0.5 M.

Molarity – Molarity is a measure of concentration defined as the number of moles of solute per liter of solution.
