A stock solution contains 51.24 g of barium hydroxide in 1.20 L of solution. How do I make 1.00 L of 0.100 mol/L barium hydroxide from the stock solution?
You must dilute 401 mL with enough water to make 1.00 L of solution.
Step 1. Calculate the molarity of the stock solution.
Moles of Ba(OH)₂ =
Step 2. Calculate the volume of stock solution that is needed.
So, to make your solution, you would dilute 401 mL of stock solution with enough water to make 1.00 L.
