What is the circumference of a bastketball?
what is SOLUBILITY?
the ability of a SOLUTE to dissolve in a SOLVENT
solubility depends upon what?
what is SATURATION POINT?
achieved when the max amount of solute has dissolved in the solvent
water volume conversions
1000ml = 1L
1gm of H20 = 1 cm3 (cubic centimeter)
1 cm3 (cc) = 1 ml
1000ml = 1L = 1000 cm3 = 1000 cc = 1000ml
formula for CONCENTRATION
CONCENTRATION = AMOUNT of SOLUTE / AMOUNT of SOLVENT
15.0 gm / .1L = ?
100gm / .1L = ?
10gm / .1L = ?
what is the maximum dissolved? (not sure if this is true)
1 Mole = ?
6.02 * 10
why is the mole a magic number?
because 1 mole of any gas at S.T.P (standard temperature pressure) occupies 22.4 L
1000 cm3 = 1L so, 22.4 L = ?
1 Gopher = ?
how many gram of O-atom equal 1 mole?
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
what is 1 mole of NaCl molecules (mass = ?), if Na = 23 gm/mole and Cl = 35.5 gm/mole?
59 gm / mole
how many grams/mole is sucrose (sugar molecules)?
formula for CONCENTRATION MOLARITY
CONCENTRATION (molarity) = # of moles of solute / liters of solvent (H2O)
what are two main classes of chemical RXNs?
1. acid - base rxn
2. oxidation - reduction
