What volume of 0.5 M NaCl solution contains 1 mole of NaCl?
1 L
2 L
0.5 L
0.25 L
Using the formula Molarity (M) = moles/volume (L), we have 0.5 M = 1 mole/volume. Therefore, volume = 1 mole / 0.5 M = 2 L.

Q: What volume of 0.5 M NaCl solution contains 1 mole of NaCl?
Solution: Using the formula Molarity (M) = moles/volume (L), we have 0.5 M = 1 mole/volume. Therefore, volume = 1 mole / 0.5 M = 2 L.
Steps: 6
Step 1: Understand that Molarity (M) is a way to express the concentration of a solution. It tells us how many moles of solute are in one liter of solution.
Step 2: Identify the given information: We have a 0.5 M NaCl solution and we want to find out how much volume contains 1 mole of NaCl.
Step 3: Use the formula for Molarity: Molarity (M) = moles / volume (L). Here, we know M = 0.5 and moles = 1.
Step 4: Rearrange the formula to find volume: volume = moles / Molarity.
Step 5: Substitute the values into the rearranged formula: volume = 1 mole / 0.5 M.
Step 6: Calculate the volume: 1 / 0.5 = 2. This means the volume is 2 liters.
