1. A 0.107 g sample of an unknown diprotic acid is titrated to the equivalence point using 50.0 mL of 0.206 M NaOH. Calculate the molar mass of the acid.
0.00515 g 20.8 g 0.0103 g 36.5 g 147 g

2. Molarity is measured in:
moles/L moles/mL mL/moles L/moles moles/volume

3. Which statement is false:
if a nonvolatile solute is added to a solvent, the vapor pressure of the solvent is lowered DHsolution">salts have a low DHsolution the amount of gas dissolved is directly proportional to the pressure of the gas above the solution heating always helps the solute dissolve in the solvent All statements are FALSE

4. Which of the following would serve as the best electrical conductor (assuming constant molarities)?
HC2H3O2 H2O H2CO3 H2SO4 HF

5. Which statement concerning the formation of a solution is FALSE?
the solute particles must overcome its intermolecular forces the resulting solution must overcome its intermolecular forces before forming into an ideal solution the solvent overcome its intermolecular forces the solute and solvent interact to form a solution all statements are true
