1. 1.00 * 10-3 of compound A was dissolved in enough water to make 1.00 mL of solution. The osmotic pressure of this solution was found to be 1.12 torr at 25oC. Calculate the molar mass.
6.01 * 10-5 g 1.66 * 104 g 1.66 g 6.01 g 5.12 g

2. Molality is measured in:
L/moles moles/L moles solute/kg solvent moles solute/ moles solvent + solute g/L

3. 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

4. Van't Hoff's factor, i is incoporated into some equations due to
a constant value that adjust for the pressure in the lab some electrolytes break up into ions a correction factor that makes data match up with hypothesis Van't Hoff factor I is a constant that corrects all osmotic equations none of the above

5. When a liquid-solution obeys Raoult's Law, it's called a/an:
perfect solution Raoult's solution ideal solution a solution that obeys Raoult's law none of the above
