Question 1

What is the concentration of O₂(g) in water at 25°C exposed to a partial pressure of oxygen of 325 mmHg? The Henry's law constant for oxygen gas at 25°C is 1.3 × 10^–3 mol/L·atm.

Question 2

0.102 g of an unknown compound dissolved in 100. mL of water has an osmotic pressure of 28.1 mmHg at 20°C. Calculate the molar mass of the compound.
◦ 727 g/mol
◦ 663 g/mol
◦ 1.10 × 10² g/mol
◦ 1.15 g/mol
◦ 0.872 g/mol
