1. How much sugar is there in 100 mL of a 10 percent aqueous sugar solution? What is the solvent in this solution?
2. What are the relative numbers of H3o+ and OH- ions in a acidic, an alkaline, and a neutral solution?
3. How many times more hydroxide ions are there in a solution with a pH of 9 than in a solution with a pH of 3?
4. If a solution has a pH of 7.5, what would its new pH be if the concentration of H3O+ ions in the solution were increased by 100 times?

I've stuck at this question for half an hour now. All my book talks about is organic molecules and other stuff, but no inorganic molecules. It's part of my biology homework. And don't say to look for it myself. I've searched the internet, looked in my mom's college biology books but could not find anything! Please help!
