Calculation of Molality and Mole Fraction of Urea in Aqueous Solution:
Step 1: Calculation of moles of Urea
Moles of Urea = Mass of Urea/Molar Mass of Urea
Moles of Urea = 3/60
Moles of Urea = 0.05
Step 2: Calculation of Mass of Solvent
Mass of Solvent = Mass of Water
Mass of Solvent = 250g
Step 3: Calculation of Molality of Urea
Molality (m) = Moles of Solute/Mass of Solvent (in kg)
Molality (m) = 0.05/0.25 (250g = 0.25kg)
Molality (m) = 0.2 mol/kg
Step 4: Calculation of Mole Fraction of Urea
Mole fraction (χ) = Moles of Urea/(Moles of Urea + Moles of Water)
Moles of Water = Mass of Water/Molar Mass of Water
Moles of Water = 250/18
Moles of Water = 13.89
Mole fraction (χ) = 0.05/(0.05 + 13.89)
Mole fraction (χ) = 0.0036
Final Answer:
The molality of Urea in the given solution is 0.2 mol/kg and the mole fraction of Urea is 0.0036.
Step 1: Calculation of moles of Urea
Moles of Urea = Mass of Urea/Molar Mass of Urea
Moles of Urea = 3/60
Moles of Urea = 0.05
Step 2: Calculation of Mass of Solvent
Mass of Solvent = Mass of Water
Mass of Solvent = 250g
Step 3: Calculation of Molality of Urea
Molality (m) = Moles of Solute/Mass of Solvent (in kg)
Molality (m) = 0.05/0.25 (250g = 0.25kg)
Molality (m) = 0.2 mol/kg
Step 4: Calculation of Mole Fraction of Urea
Mole fraction (χ) = Moles of Urea/(Moles of Urea + Moles of Water)
Moles of Water = Mass of Water/Molar Mass of Water
Moles of Water = 250/18
Moles of Water = 13.89
Mole fraction (χ) = 0.05/(0.05 + 13.89)
Mole fraction (χ) = 0.0036
Final Answer:
The molality of Urea in the given solution is 0.2 mol/kg and the mole fraction of Urea is 0.0036.
