Final answer:
To calculate the osmotic pressure of a solution, we can use the formula: π = (n/V)RT. In this case, we calculate the number of moles of ethylene glycol and then use the formula to find the osmotic pressure. The osmotic pressure of the solution is 2.95 atm.
Step-by-step explanation:
To calculate the osmotic pressure of a solution, we can use the formula:
π = (n/V)RT
Where π is the osmotic pressure, n is the number of moles of solute, V is the volume of the solution, R is the ideal gas constant, and T is the temperature in Kelvin.
To start, we need to calculate the number of moles of ethylene glycol:
First, convert the mass of ethylene glycol to moles:
1.5 g C₂H₆O₂ * (1 mol C₂H₆O₂ / 62.07 g C₂H₆O₂) = 0.0242 mol C₂H₆O₂
Now, calculate the osmotic pressure:
π = (0.0242 mol / 0.0500 L) * (0.0821 atm·L/mol·K) * (298 K) = 2.95 atm
