If the solubility of a compound is 30 grams per liter, how much solid is left undissolved if you mix 30 g of the compound in 0.33 L of solution?
 
  A) 20 g
  B) 10 g
  C) 0 g
  D) 30 g
  E) 33 g

Question 2

Based on atomic size, which would you expect to be more soluble in water: helium, He, or nitrogen, Image?
 
  A) Although He is smaller, its outer orbital is filled and the atom will have little attraction to the water molecules.
  B) Since He atoms are smaller, more of them can fit into solution, so it has a higher solubility in water.
  C) Nitrogen atoms are bigger and so nitrogen molecules should be more soluble in water due to greater dipole-induced dipole attractions.
  D) He atoms are bigger and so helium molecules should be more soluble in water due to greater dipole-induced dipole attractions.
