What would be the osmotic pressure of a solution containing 5.85g NaCl...
Calculation of osmotic pressure of the given solution involves the following steps:
Determining the number of particles in solution:
- NaCl dissociates into two ions (Na+ and Cl-) in the solution.
- Sugar does not dissociate in solution.
- Therefore, total number of particles (i) in solution = 2 + 1 = 3
Calculating the molarity of the solution:
- Molarity (M) = moles of solute / volume of solution in liters
- Moles of NaCl = 5.85 g / 58.44 g/mol = 0.1 mol
- Moles of sugar = 3.42 g / 342.3 g/mol = 0.01 mol
- Total moles of solute = 0.1 + 0.01 = 0.11 mol
- Volume of solution = 500 mL = 0.5 L
- Molarity of solution = 0.11 mol / 0.5 L = 0.22 M
Calculating the van't Hoff factor (i) of the solute:
- NaCl dissociates into two ions, so i = 2
- Sugar does not dissociate, so i = 1
Calculating the osmotic pressure (π) of the solution:
- π = iMRT, where R is the gas constant (0.0821 L atm mol^-1 K^-1) and T is the temperature in Kelvin (27°C = 300 K)
- For NaCl: π = 2 x 0.22 x 0.0821 x 300 = 10.34 atm
- For sugar: π = 1 x 0.22 x 0.0821 x 300 = 1.81 atm
- Total osmotic pressure = 10.34 + 1.81 = 12.15 atm
Therefore, the osmotic pressure of the given solution containing 5.85g NaCl and 3.42g sugar in 500 mL at 27⁰C is 10.34 atm (Option B).
Determining the number of particles in solution:
- NaCl dissociates into two ions (Na+ and Cl-) in the solution.
- Sugar does not dissociate in solution.
- Therefore, total number of particles (i) in solution = 2 + 1 = 3
Calculating the molarity of the solution:
- Molarity (M) = moles of solute / volume of solution in liters
- Moles of NaCl = 5.85 g / 58.44 g/mol = 0.1 mol
- Moles of sugar = 3.42 g / 342.3 g/mol = 0.01 mol
- Total moles of solute = 0.1 + 0.01 = 0.11 mol
- Volume of solution = 500 mL = 0.5 L
- Molarity of solution = 0.11 mol / 0.5 L = 0.22 M
Calculating the van't Hoff factor (i) of the solute:
- NaCl dissociates into two ions, so i = 2
- Sugar does not dissociate, so i = 1
Calculating the osmotic pressure (π) of the solution:
- π = iMRT, where R is the gas constant (0.0821 L atm mol^-1 K^-1) and T is the temperature in Kelvin (27°C = 300 K)
- For NaCl: π = 2 x 0.22 x 0.0821 x 300 = 10.34 atm
- For sugar: π = 1 x 0.22 x 0.0821 x 300 = 1.81 atm
- Total osmotic pressure = 10.34 + 1.81 = 12.15 atm
Therefore, the osmotic pressure of the given solution containing 5.85g NaCl and 3.42g sugar in 500 mL at 27⁰C is 10.34 atm (Option B).
