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) In chemistry, a hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative "donor" atom or group (Dn), and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac). Such an interacting system is generally denoted Dn−H···Ac, where the solid line denot… pothos live indoor plant https://roschi.net

WebHydrogen bonding in water is cooperative. That is, an H- bonded water molecule serving as an acceptor is a better H-bond donor than an unbonded molecule (and an HgO molecule serving as an H-bond donor becomes a better H- bond acceptor ). Thus, participation in H bonding by HgO molecules is a phenomenon of mutual reinforcement.
