The total number of valence electrons is 20.(1 from hydrogen, 5 from nitrogen, and 7 from each fluorine so 14 for both) connect all the atoms with a single bond( each bond counts as 2) so far there is 6 electrons so you need to fill in the rest of the 14 and you get the result in the picture.

A high concentration of water has <u>fewer</u> dissolved particles than a low water concentration.
Most cell membranes are not as easily permeable to many dissolved compounds as water is. There is a quick and constant flow of water. From one area with less dissolved matter to another with more, water transports NET. Or, if you want, from an area with a lot of water to one with little water. The terms isotonic, hypotonic, and hypertonic refer to the concentration of dissolved material. In a medium, such as the extracellular fluid, every distinct material has a concentration gradient that is unique from the gradients of other substances. Every substance will diffuse in line with that gradient as well.
