What is the osmotic pressure of a solution of sucrose containing 68.4 g of its per litre of solution?

• Correct Answer: B

  Solution :

           \[\pi =CRT\]                 \[\pi =\frac{w\times R\times T}{mV}=\frac{68.4\times 0.0821\times 273}{342}\]= 4.92 atm

• Correct Answer: B

  Solution :

             \[\pi =\frac{n}{V}RT=\frac{m/MRT}{V}\]                                 \[\frac{600}{760}=\frac{20\times 0.0821\times 288\times 1000}{500\times M}\]; \[M=1200\]
