Hello, Can you please answer #'s 1, 3, 5, 7, 9, 11, and 12? Thank you!

1. How many moles and millimoles of benzoic acid are contained in 2.00 g of the pure acid? 2. How many grams of Na* are contained in 25.0 g of Na2SO4 3. Describe the preparation of 2.00 liters of 0.108 M BaCl₂ from BaCl2.2H₂O 4. Describe the preparation of 500 ml of 0.0740 M CI solution from solid BaCl₂.2H₂O 5. What is the molarity of K+ in an aqueous solution that contains 63.3 ppm of K3Fe(CN)6 ? 6. Calculate the p-value for each ion in a solution that is 2.00 x 10 ³M in NaCl and 5.4 x 10+ M in HCI 7. Calculate the molar concentration of Ag+ in a solution that has a pAg of 6.372 8. Exactly 0.1120 g of pure Na2CO3 was dissolved in 100.0 ml of of 0.0497 M HCl. What mass of CO₂ was evolved? 9. How many grams of solute are contained in 450 ml of 0.164 M H₂O2 ? 10. Calculate the molarity of a solution made by dissolving 2.42 g of ribidium chloride, RbCl in enough water to make 250.0 ml of solution. 11. The laboratory acid called "concentrated" sulfuric acid is 18M H₂SO4. How can 500.0 ml of 3.0 M aqueous acid be prepared from "concentrated" sulfuric acid? 12. A solution is prepared by mixing 500.0 ml of a 1.00 M solution of Mg(NO3)2 with 250.0 ml of a 2.00 M solution of AgNO3. What are the molar concentrations of the Mg²+ ions, the Ag+ ions, and the NO3 -ions in the final mixture?
