Study questions 3 1. A pH of 3 indicates that the concentration of H+ is: c. 10exp-3 M 2. If he concentration of H+ is very high the concentration of OH- will be: c. very low 3. A mole of a compound defines a number of molecules: c. fixed for any compound 4. Molarity is defined as the number of: c. moles in a L of solution 5. The atomic weight of K is 39, and of Cl is 23. What amount of KCl is required to make 1L of 0.5M solution? d. 31 The molecular mass (=weight) of guanosine is 283. The single stranded DNA polymer ATGC has

Unformatted text preview: a molecular mass of 1173. The following two questions relate to this statement: 6. If you add 141.5 g of guanosine to 500 ml of water the molarity of that solution is e. 1 7. Your task is to add an amount of ATGC polymer to 1 L of water such that the guanosine com-ponent of the ATGC polymer has an identical concentration to that of the free guanosine in ques-tion 6. How many g of ATGC do you add? e. 1173...
