Question
Part A (Figure 1) shows two compartments separated by a semipermeable membrane that is permeable to the solvent water but not to the solute. The concentration of the solute is 135 mM on the right side of the membrane and 70 mM on the left side. What is the height difference h between the two water surfaces at a temperature of 20°C? Express your answer to two significant figures and include the appropriate units. μA ? h= Value Units Submit Request Answer Part B Figure < 1 of 1 > Suppose that the membrane is suddenly made permeable to the solute, as can happen in cells when voltage-gated ion channels open, and that the diffusion constant for the solute through the membrane is 5.0 x 10-10 m²/s. What is the initial rate of flow of the solute in molecules/s through 10 µm² of a 7.0-nm-thick membrane? These values are comparable to the surface area and thickness of a cell membrane. Express your answer to two significant figures and include the appropriate units. IVE ΑΣΦ ? molecules/s dt. Two containers with a liquid separated by a membrane Submit Request Answer
