A solution of sucrose (molar mass = 342 g/mol) is prepared by dissolving 68.4 g of it per litre of the solution, what is its osmotic pressure (R =0.082 "lit. atm." k^(-1)mol^(-1))at 273 K

Answer»

6.02 ATM
4.48 atm
4.04 atm
5.32 atm

Solution :`pi=CRT`
`pi=(w XX R xx T)/(MV)=(68.4xx0.0821xx273)/(342)=4.48` atm
