A solution contains 5% w/v Al2(SO4)3.14H20 (MW = 600). Assuming there is complete ionization, calculate the osmolarity of the solution.

When 2.73 g2.73 g of a nonelectrolyte solute is dissolved in water to make 815 mL815 mL of solution at 21 °C,21 °C, the solution exerts an osmotic pressure of 961 torr.961 torr. What is the molar concentration of the solution?

What is the osmotic pressure (in atm) of a 1.56 M aqueous solution of urea Round your answer to 3 significant digits. II = atm x10 X Ś (NH,),CO] at 16.0 °C?

A solution is prepared by dissolving 40.00 g of NaCl (f.w. = 58.44 g mol–1), a non-volatile solute, in enough water (m.w. = 18.02 g mol–1) to result in exactly 1 L of solution at 25 °C. Assume the density of the solution is that of pure water (dsolution = 1.000 g mL–1). The ebullioscopic constant (Kb) for water is 0.513 °C m–1. The cryoscopic constant (Kf) for water is 1.86 °C m–1. The vapor pressure of pure water is 0.0313 atm. Find the freezing point of the solution(in C to 2 decimal places)
