Answer:
a)905,89 atm of pressure will be generated at 298K.
b)The sap of tree can rise upto 9,357.84 meters.
Explanation:
a)
Effective concentration of sap = c = 37 M
Osmotic pressure generate at 298K = [tex]\pi [/tex]
Temperature ,T = 298 K
[tex]\pi =cRT[/tex]
[tex]\pi =37 mol/L\times 0.08216 atm L/mol L\times 298 K[/tex]
[tex]\pi =905.89 atm[/tex]
905,89 atm of pressure will be generated at 298K across the endodermis root membrane.
b)
Given that 1.0 at of pressure raises the volume of water upto height of 10.33 m
Then 905.89 atm of pressure will raise the height of water upto:
[tex]\frac{10.33}{1.0}\times 905.89 m=9,357.84 m[/tex]
The sap of the tree can rise upto 9,357.84 meter.
