Answer: Molar concentration of the tree sap have to be 0.783 M
Explanation:
To calculate the concentration of solute, we use the equation for osmotic pressure, which is:
where,
= osmotic pressure of the solution = 19.6 atm
i = Van't hoff factor = 1 (for non-electrolytes)
R = Gas constant = 
T = temperature of the solution = ![32^oC=[273+32]=305K](https://tex.z-dn.net/?f=32%5EoC%3D%5B273%2B32%5D%3D305K)
Putting values in above equation, we get:
Thus the molar concentration of the tree sap have to be 0.783 M to achieve this pressure on a day when the temperature is 32°C
Calcium chloride is the solute because it was dissolved in water.
Therefore water is the solvent.
Gynosperms is a plant that has seeds unprotected by an ovary or fruit and Gymnosperms include the conifers and cycads and angiosperms are a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, and most trees.
Cells have limitations, if the cell is stronger it targets other cells , when a cell is weak it possibly mean it’s disease.
