Question 1

A 0.20 M solution of MgSO4 has an observed osmotic pressure of 7.6 atm at 25°C. Determine the observed van 't Hoff factor for this experiment.

◦ 19
◦ 0.31
◦ 1.6
◦ 1.8
◦ 2.0

Question 2

A 2.61-gram sample of a compound is dissolved in enough water to form 100.0 mL of solution. This solution has an osmotic pressure of 25.0 torr at 25°C. If it is assumed that each molecule of the solute dissociates into two particles (in this solvent), what is the molar mass of this solute?

◦ 5.11 × 101 g/mol
◦ 3.26 × 103 g/mol
◦ 1.94 × 103 g/mol
◦ 3.88 × 104 g/mol
