Calculation of Osmotic Pressure
To calculate the osmotic pressure, we need to use the formula: π = iMRT, where π is the osmotic pressure, i is van't Hoff factor, M is the molarity of the solution, R is the gas constant, and T is the temperature.
Given data:
Molarity of sugar solution = 0.3 M
Molarity of KCl solution = 0.1 M
Temperature = body temperature
Determination of van't Hoff Factor
The van't Hoff factor (i) is the number of ions dissociated in a solution. Since both sugar and KCl are non-electrolytes, their van't Hoff factor is 1.
Calculation of Osmotic Pressure
π = iMRT
π = (1)(0.3 M)(0.0821 L•atm/mol•K)(310 K)
π = 7.47 atm
The osmotic pressure when the cell is in the sugar solution is 7.47 atm.
Determination of Osmotic Pressure in KCl Solution
When the cell is placed in 0.1 M KCl solution, the osmotic pressure can be calculated using the same formula.
π = iMRT
π = (1)(0.1 M)(0.0821 L•atm/mol•K)(310 K)
π = 2.49 atm
The osmotic pressure in KCl solution is 2.49 atm.
Therefore, the correct answer is option (d) 2.46 atm.
