WebNaCl has a molecular weight of 58.5 amu. Explain specifically how you would make 0.15 molar solution of NaCL. To make a .15 M solution of NaCl, you would measure 8.78 g of NaCl, add it to a flask, and add enough water until you reach a volume of 1 liter. The osmotic pressure of .15 M NaCl is .30 osmols. Web9 de dez. de 2010 · Osmosis is very similar to normal diffusion, but osmosis is only the movement of water through a "partially permeable membrane" where as simple diffusion is the movement of anything from an area ...

WebIn cells, some molecules can move down their concentration gradients by crossing the lipid portion of the membrane directly, while others must pass through membrane proteins in a process called facilitated diffusion. Here, we’ll look in more detail at membrane permeability and different modes of passive transport. Web3. The lighter the molecule, the greater the rate of diffusion. 4. The faster molecules move, the greater the rate of diffusion. Osmosis is the diffusion of water across a semipermeable membrane. The semipermeable membrane is necessary for osmosis because it restricts the movement of certain solutes, allowing the solvent to pass through. c\u0026c generals 50 colors

How are osmosis and diffusion alike? - Brainly

WebIn the case of osmosis and facilitated diffusion; they have some similarities as well as some differences. Osmosis is the spontaneous movement of water molecules across a semi permeable membrane from a region … WebThe transport of water and salt through the active layer of RO membranes governs the membrane desalination performance. The widely accepted theory or mechanism to describe water and salt transport in RO membranes is the solution-diffusion (SD) model, which was proposed over half a century ago ().This model assumes that the membrane active layer … easley self storage
