Final answer:
To identify the unknown compound, we can use the osmotic pressure equation and compare the molar concentration to the given value. The compound with the correct concentration is C₆H₁₂O₆ (option c).
Step-by-step explanation:
The osmotic pressure of a solution is related to the concentration of the solute particles in the solution. We can use the equation II = MRT, where II is the osmotic pressure, M is the molar concentration of the solute, R is the ideal gas constant, and T is the temperature in Kelvin.
To find the concentration of the unknown compound, we need to convert the given mass (24.6 g) to moles using the molar mass of the compound. Then, we can divide the number of moles by the volume of the solution in liters to obtain the molar concentration. Comparing the molar concentration to the given osmotic pressure, we can identify the compound as C₆H₁₂O₆ (option c).
