1. What is the circumference of a bastketball?
• 75 cm.
2. what is SOLUBILITY?
the ability of a SOLUTE to dissolve in a SOLVENT
3. solubility depends upon what?
temperature
4. what is SATURATION POINT?
achieved when the max amount of solute has dissolved in the solvent
5. water volume conversions
• 1000ml = 1L
• 1gm of H20 = 1 cm3 (cubic centimeter)
• 1 cm3 (cc) = 1 ml

1000ml = 1L = 1000 cm3 = 1000 cc = 1000ml
6. formula for CONCENTRATION
CONCENTRATION = AMOUNT of SOLUTE / AMOUNT of SOLVENT
7. CONCENTRATION

15.0 gm / .1L = ?
1500 gm/L
8. CONCENTRATION

100gm / .1L = ?
1000 gm/L
9. CONCENTRATION

10gm / .1L = ?
100 gm/L
10. what is the maximum dissolved? (not sure if this is true)
200 gm/L
11. 1 Mole = ?
6.02 * 10 23 Particles
12. why is the mole a magic number?
because 1 mole of any gas at S.T.P (standard temperature pressure) occupies 22.4 L
13. 1000 cm3 = 1L so, 22.4 L = ?
22,400 cm3
14. 1 Gopher = ?
10 particles
15. how many gram of O-atom equal 1 mole?
16 grams
16. if 16 grams of O-atom equals 1 mole
a. how much is 32 grams of O-atom?
b. how much is 22.2 grams of NE-atom?
• a. 2 moles
• b. 1 mole
17. what is 1 mole of NaCl molecules (mass = ?), if Na = 23 gm/mole and Cl = 35.5 gm/mole?
59 gm / mole
18. how many grams/mole is sucrose (sugar molecules)?
342 gm/mole
19. formula for CONCENTRATION MOLARITY
CONCENTRATION (molarity) = # of moles of solute / liters of solvent (H2O)
20. what are two main classes of chemical RXNs?
• 1. acid - base rxn
• 2. oxidation - reduction
