Question

Osmosis is the process responsible for carrying nutrients and water from groundwater supplies to the upper parts of trees. The osmotic pressures required for this process can be as high as 19.1 atm . What would the molar concentration of the tree sap have to be to achieve this pressure on a day when the temperature is 32 ∘C ? Express your answer to three significant figures and include the appropriate units. View Available Hint(s)

Answer 1

`M=0.763(mol)/(L)=0.763M`

Step-by-step explanation:

Hello,

In this case, as the osmotic pressure (π) is widely known as a colligative property, we can see that the solution in this case is formed by water and tree sap, that is mathematically defined by:

`\pi =iMRT`

Thus, since tree sap is a covalent substance that is nonionizing, we can infer its van't Hoff factor to be 1, therefore, for the given osmotic pressure and temperature, we can compute the molar concentration (in molar units mol/L) as follows:

`M=(\pi )/(RT) =(19.1atm)/(0.082(atm*L)/(mol*K)*(32+273.15)K) \\\\M=0.763(mol)/(L)=0.763M`

Best regards.
