What is the circumference of a bastketball? 75 cm. what is SOLUBILITY? the ability of a SOLUTE to dissolve in a SOLVENT solubility depends upon what? temperature what is SATURATION POINT? achieved when the max amount of solute has dissolved in the solvent water volume conversions 1000ml = 1L1gm 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 CONCENTRATION 15.0 gm / .1L = ? 1500 gm/L CONCENTRATION 100gm / .1L = ? 1000 gm/L CONCENTRATION 10gm / .1L = ? 100 gm/L what is the maximum dissolved? (not sure if this is true) 200 gm/L 1 Mole = ? 6.02 * 10 23 Particles 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 = ? 22,400 cm3 1 Gopher = ? 10 particles how many gram of O-atom equal 1 mole? 16 grams 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 molesb. 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)? 342 gm/mole 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 AuthormLy ID18958 Card SetCHEMISTRY FINAL Descriptionchemistry Updated2010-05-12T04:58:39Z Show Answers
