80 POINTS 1. 14.07g of solid sucrose (C12H22O11) are dissolved in 0.35 L of water. What is the molarity of the solution?

2. What is the molarity of a sucrose solution with a concentration of 4.5 ppm (mg/L)?

3. What is the molarity of the same sucrose solution if you dilute 40 mL of it into a 500 mL volumetric flask?

4. A cosmetic chemist is making a lotion which can have a maximum concentration of 0.04 M glycerol (C3H6O3). If each bottle of lotion is 0.5 liters, how many moles could each bottle have at the maximum?

5. What is the pH of an aqueous solution of the strong acid, Perchloric Acid (HClO4), with a concentration of 0.007 M?

6. In the following reaction, how many moles of HNO3 are needed to react with 7 moles of KOH to achieve a pH of 7.00?
