Problem 19
If \(25.0 \mathrm{~g}\) of \(\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}\) are dissolved in \(\mathrm{H}_{2} \mathrm{O}\) to make \(0.100 \mathrm{~L}\) of solution, what is the osmotic pressure of this solution at \(25^{\circ} \mathrm{C?}\)
Problem 20
If \(2.33 \mathrm{~g}\) of \(\mathrm{C}_{27} \mathrm{H}_{46} \mathrm{O}\) are dissolved in liquid \(\mathrm{CS}_{2}\) to make \(50.00 \mathrm{~mL}\) of solution, what is the osmotic pressure of this solution at \(298 \mathrm{~K} ?\)
Problem 22
The osmotic pressure of blood is about 7.65 atm at \(37^{\circ} \mathrm{C}\). What is the approximate concentration of dissolved solutes in blood? (There are many different solutes in blood, so the answer is indeed an approximation.)
