Question

A dilute aqueous solution of an organic compound soluble inwater is formed by dissolving 2.35 g of the compound in water toform 0.250 L solution. the resulting solution has an osmoticpressure of 0.605 atm at 25 degrees C. Assuming that the organic compound is a nonelectrolyte, whatis its molar mass?

Assuming that the organic compound is a nonelectrolyte, whatis its molar mass?

Explanation / Answer

Molar Mass= dRT/P where d=density = Mass/Volume            R=constant            T=temp in kelvin            P=pressure M= {2.35 g/0.25 L * 0.082058 atm LK-1 mol-1 *298.15K}/0.605 atm Molar Mass = 380 g/mol
