The ionic formula of sodium oxide would be Na20
Osmosis is the movement of water and is always the movement in the membrane. Diffusion does not need a membrane to make molecules and Diffusion is the movement of molecules.
hoped this helped, good luck
Amount of NH3 = 6.39 mol
Ratio of NH3 : Ratio of product
4 : 10
Hence, amount of product formed = 6.39/4 * 10 = 15.975mol = 16.0mol (3sf)
