A tree is 10.0 m tall.
(a) What must be the total molarity of the solutes if sap rises to the top of the tree by osmotic pressure at 20°C? Assume the groundwater outside the tree is pure water and that the density of the sap is 1.0 g/mL. (1 mm Hg =13.6 mm H₂O.)
(b) If the only solute in the sap is sucrose, C₁₂H₂₂O₁₁, what is its percent by mass?
