Each O has two lone pairs which can accept two hydrogen bonds, so a group of water molecules would aim for, but not be able to maintain, a tetrahedral arrangement about each other. On average, above 4 C th...

Webb14 okt. 2024 · Water Properties & Structure. We think of water as common and familiar, but chemically it is one strange molecule. Most chemicals shrink and sink when they freeze, but water expands and floats ... WebbTo find out how many moles of water in 3 cups just divide 720 by 18.0015 which gives you 39.9667 moles of water. This gives you 240.685 * 10^32 or 2.40685 * 10^34 water molecules. Since there are 3 atoms in a water molecule multiply the number of water molecules by 3 giving you 7.2206 * 10^34 atoms.

Webb8. the shape or molecular geometry of a water molecule is tetrahedral. Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°. Answer: tetrahedral.
