1. How many milliliters of a stock solution of 11.6 M HNO3 would you have to use to prepare 0.300 L of 0.550 M HNO3 ?
2. If you dilute 27.0 ml of the stock solution to a final volume of 0.400 L, what will be the concentration of the diluted solution?
3. Calculate the molarity of a solution made by dissolving 0.810 grams of Na2SO4 in enough water to form exactly 890 ml of solution.
4. How many moles of KMnO4 are present in 300 ml of a 5.00×10^(-2) M solution?
5. How many milliliters of 11.8 M HCl solution are needed to obtain 0.200 mol of HCl?
