The correct answer is Option A.
Π = (W / M * V) * R * T
Π = (3.42 / 345 * 1 L) * 300 K * 0.0821
    = 0.02463 atm

°C?

To solve this problem, we need to use the formula for osmotic pressure:

π = MRT

Where:
π = osmotic pressure (in atm)
M = molarity of the solution (in mol/L)
R = gas constant (0.0821 L·atm/mol·K)
T = temperature (in Kelvin)

First, we need to calculate the molarity of the solution:

M = moles of solute / volume of solution (in L)

The molecular weight of cane sugar (also known as sucrose) is 342.3 g/mol. Therefore, the number of moles of sucrose in 3.42 g is:

moles of sucrose = mass of sucrose / molecular weight of sucrose
moles of sucrose = 3.42 g / 342.3 g/mol
moles of sucrose = 0.01 mol

The volume of the solution is given as 1 L. Therefore:

M = 0.01 mol / 1 L
M = 0.01 M

Now we can calculate the osmotic pressure using the formula:

π = MRT
π = 0.01 M × 0.0821 L·atm/mol·K × (273 + 27) K
π = 2.54 atm

Therefore, the osmotic pressure of the solution containing 3.42 g of cane sugar in 1 litre solution at 27°C is 2.54 atm.
