# At 300 K, 36 g of glucose present in a litre of its solution has an osmotic pressure of 4.98 bar. If the osmotic pressure of the solution is 1.52 bars at the same temperature, what would be its concentration?

$\begin{array}{1 1}0.061M\\0.071M\\0.051M\\0.081M\end{array}$

$\pi =CRT$
$4.98 = \large\frac{36}{180}$$\times R\times 300$
$4.98=60R$-----(i)
In second case :
$1.52=C\times R\times 300$-----(ii)
Dividing (ii) by (i)
We get $C=0.061M$
