Question 1

1. What is the molality of a solution of 5.00 g of tridecanoic acid dissolved in 20.0 g of
stearic acid?
2. Calculate the observed change in the freezing point (AT:) from pure stearic acid to
the mixture described in question 1.
3. Do colligative properties depend on the number of particles dissolved, the identity
of the particles dissolved, or both?
4. Find the SDS for stearic acid. What hazards are associated with stearic acid?
Terms You Should Know
A solution is a mixture of a solvent (the more abundant chemical) and a solute (the less
abundant chemical).
Colligative Properties, such as vapor pressure lowering, freezing point depression, boiling
point elevation, and osmotic pressure, are properties that depend on the concentration of
solute in solution, but not on the identity of the solute.

» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant.
