1. Ifyou wanted to make a 4 M NaCl solution and you wanted a full Liter of it, how would you make it? Describe all of the steps. (Remember from lab, molecular weight of NaCl is 58.44) 2. Now describe how you would dilute this 4 MNaCl solution by a 1:10 dilution -how would you do this? Again, make 1 Liter. 3. Suppose you wanted a 2: 50 dilution of a stock solution, but you wanted 200 mL of it....

Calculate how much KOH you will need to weigh out to make 250 mL of a 0.2M KOH solution. How much potassium hydrogen phthalate (molar mass 204.23 g/mol) do you need to weigh out if you want to use 20.00 mL of your standard 0.2000 M KOH solution to titrate the potassium hydrogen phthalate sample? Note: potassium hydrogen phthalate has ONE hydrogen that reacts with KOH. We often use KHP as our "simplified formula" for potassium hydrogen phthalate rather than...
