WebTo 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. ( 6 votes)
WebDraw a proposed structure for chains of HOF molecules in the crystalline state. The bond angle in HOF is 101 degrees. Hypofluorous acid (HOF) is the simplest possible compound that allows comparison between fluorine and oxygen in their abilities to form hydrogen bonds. Although F attracts electrons more strongly than O, solid HOFunexpectedly ... WebMolecules which are capable of hydrogen bonds have hydrogen atoms which are covalently bonded to highly electronegative elements (O, N, F). The presence of hydrogen bonding between molecules of a substance indicates that the molecules are polar. This means the molecules will be soluble in a polar solvent such as water..
