Finding the osmotic pressure of solution

hey
Explanation: 
Answer: 

Determine the molarity of the solution (MM C12H22O11 = 342.3 g /mol).Then substitue into osmotic pressure equation to obtain osmotic pressure.

Molairy (M) = 50.0g/(342.3 g/mol)/1.00 L = 0.146 mol/L

Π = 0.146 mol/l x 0.00820 L.am/mol.K x 288 K = 3.45 atm
