X g of a non-electrolyte compound (molar mass = 200) are dissolved in 1.0 litre of 0.05 M NaCl aqueous solution. The osmotic pressure of this solution is found to be 4.92 atm at 27∘C. Calculate the value of X. Assume complete dissociation of NaCl and ideal behaviour of this solution. (R=0.082 litre atm mol−1 K−1)
