C) a supersaturated solution D) a concentrated solution E) a saturated solution 4) To increase solubility of a gas into a liquid the most, then A) increase the temperature and lower the pressure. B) increase the temperature and raise the pressure. C) decrease the temperature and raise the pressure D) decrease the temperature and lower the pressure E) neither pressure or temperature affects solubility 5) Determine the Henry's law constant for ammonia in water at 25 C if an ammonia pressure produces a solution with a concentration of 1.3 M A) 59 M/atm B) 0.017 M/atm C) 0.029 M/atm D) 35 M/atm E) 0.038 M/atm 6) Give the term for the amount of solute in moles per kilogram of solvent.

A) 0.125 moles B) 2.00 molesExplanation / Answer
Answer 1 ) major force between the molecules of pentane is dispersion force because C-H bond is not polar and has no charge so there will be no dipoles Correct abswer is option B
Answer 2) A solution containing less than the equilibrium amount is called unsaturated solution
Answer 3) A solution containing more than the equilibrium amount is called supersaturated solution
