WebWhat is the molecular weight of the compound? The freezing point of human blood is -0.52°C. If you are preparing a solution of dextrose for injection, what mass of dextrose … Webthe freezing point depression of water in solution was –2.6°C when 1.0 g of glucose was dissolved in 10g of solvent. Calculate the expected freezing point for such solution and compare the expected freezing point to the value found experimentally. Give a plausible explanation for any discrepancies. (M.W. of glucose= 180.16g/mol; i=1).
Boiling point elevation and freezing point depression - Khan …
WebE.g. Osmotic pressure, vapor pressure, freezing point depression, boiling point elevation. The colligative properties are inter-related; if you change one, it might cause a corresponding change in others. ... (50 g dextrose)/(MW of 180) = 0.28 mol of dextrose 3. 0.28 + 55.56 = 55.84 total moles 4. (55.56)/(55.84) = 0.995 mole fraction of water WebAug 25, 2024 · If this model were perfectly correct, we would expect the freezing point depression of a 0.10 m solution of sodium chloride, with 2 mol of ions per mole of \(NaCl\) in solution, to be exactly twice that of a 0.10 m solution of glucose, with only 1 mol of molecules per mole of glucose in solution. In reality, this is not always the case. claries elmwood automotive roch ny
