Q
Q: If 0.5 moles of NaCl are dissolved in 1 liter of water, what is the concentration of NaCl in the solution?
Solution:
Concentration (M) = moles of solute / liters of solution = 0.5 moles / 1 L = 0.5 M.
Steps: 5
Show Steps
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.
