Respuesta :

osmotic  pressure  is  minimum  pressure  which  need  to applied  to  a solution  to  prevent  inward  flow of its pure  solvent across  a  semipermeable  membrane.
osmotic  pressure =cRT
c=concentration  =0.25M   or  0.25  mol/l
R=gas  constant=0.0821  atm/mol.k
T=temperature=37 +273=310k
osmotic  pressure  is  therefore
0.25 mol/L  x0.0821L.atm/mol.k  x  310k=6.36atm

Answer:

[tex]\Pi =6.4atm[/tex]

Explanation:

Hello,

The osmotic pressure equation is given by:

[tex]\Pi =iCRT[/tex]

in this case, sucrose is not ionized, so the van't Hoff factor is 1; thus, one computes the osmotic pressure directly:

[tex]\Pi =1(0.25\frac{mol}{L} )(0.0832\frac{atm*L}{mol*K})(37+273.15)K\\\Pi =6.4atm[/tex]

Best regards.
