WebAug 8, 2024 · Calculating Molar Mass. In the laboratory, freezing point or boiling point data can be used to determine the molar mass of an unknown solute. Since we know the relationship between a decrease in freezing point and the concentration of solute, if we dissolve a known mass of our unknown solute into a known amount of solvent, we can … WebWe can do this using the following equation: M = moles of solute / liters of solution. We know the mass of the protein in the solution (30.0 g), and we can calculate the number of moles of protein using the molar mass: moles of protein = mass of protein / molar mass = 30.0 g / 48800 g/mol = 6.15 x 10^-4 mol
How to Calculate Osmotic Pressure and Freezing Point from ... - Wyzant
WebWhat is the molar mass, in grams per mole, of the protein? Data: assuming the water ls pure, then the osmotic pressure π = ρ g h, where h is the height of the water, ρ is the … WebA solution is 4.00% (by mass) maltose and 96.00% water. It freezes at 0.229 C. (a) Calculate the molar mass of maltose (which is not an ionic compound). (b) The density of the solution is 1.014 g/mL Calculate the osmotic pressure of the solution. farm to table restaurants in scottsdale

WebApr 12, 2024 · Step1 concentration= .2g/10 ml = 20 g/l; Osmotic pressure =5.5/760 atm; Temp =298 K Step2 Concentration = osmotic pressure/R * T ; 20/Molar mass = 5.5/760x.082x298 Step3 Molar mass =[ 760x.082x298x20] /5.5; Calculate this value and express it in grams Step4 Mass of iron in 1 mole of Hb =[.33/100] x Molar mass of Hb … WebFeb 26, 2024 · The molar mass of the protein is 4453.7 g/mol. Explanation: Step 1: data given. Mass of the unknown protein = 5.87 mg = 0.00587 grams. volume = 10 mL. Osmotic pressure = 2.45 torr. Temperature = 25.0 °C. Step 2 = Calculate concentration. π = i*M*R*T. ⇒ π = the osmotic pressure = 2.45 torr = 2.45 / 760 atm = 0.003223684 atm. … WebFor example, higher osmotic pressure and boiling point. Abnormal Molar Masses. The theoretical values of molecular mass, when calculated from the colligative properties of solutions, are sometimes found to differ from the experimentally obtained values. These values are often referred to as abnormal molar masses. ... But while calculating the ... farm to table restaurants in williamsburg va
