Webπ = w 2 R T M 2 V. Rearranging the above equation we get, M 2 = w 2 R T π V. Thus we can calculate the molecular weight of a substance using the colligative properties of solutions. The three methods discussed above provide us with the options that are used based on the type of substance and the nature of the solvent and the degree of ... WebMay 9, 2024 · Osmotic pressure is expressed by the formula: Π = iMRT where Π is the osmotic pressure in atm, i = van 't Hoff factor of the solute, M = molar concentration in mol/L, R = universal gas constant = 0.08206 L·atm/mol·K, and T = absolute temperature in Kelvin. Step 1: Determine the van 't Hoff factor.

WebApr 13, 2005 · The Bob. To determine the molar mass of a certain protein, 1.00E-3 grams of the protein was dissolved in enough water to make a 1.00 mL solution. The osmotic pressure of this solution was found to be 1.12 torr at 25.0C. Calculate the molar mass of the protein. I assume you want help in working out the molar mass. WebOsmometry is used to determine the molecular mass, which depends on colligative properties, meaning that the number of dissolved molecules is the only factor that alters the properties of a solution. In addition, boiling point elevation, osmotic pressure, freezing point depression, and vapor pressure reduction are based on colligative ... deadline morphs
