Assertion:
The molar mass obtained for benzoic acid  in Benzene is found to be nearly twice.
Reason:
benzoic acid has the formula HOOC

Assertion: when a cell is placed in hypertonic solution it shrinks .
Reason : rivers osmosis is used for desalination of water

200 mL of an aqueous solution contains 1.26 g of protein.The osmotic pressure of the solution at 300K is found to be \( 2.57 \times 10^{-3} \)
bar. The molar mass of protein will be\( R = 0.083~\mathrm{bar \cdot mol^{-1} \cdot K^{-1}} \)
