[QUOTE="FaraDazed, post: 4570143, member: 438851"] [h2]Homework Statement [/h2] Estimate the bond energy between two water molcules (liquid) in the following way A: From the density of water and its molecular weight calculate the average distance between the molecules B:hence show that there are 10^19 molcules per m^2 of surace C:from the suraface tension of water, assuming this to be the same as the suraface energy, fine the value of U_0 [h2]Homework Equations[/h2] [tex]N_s ≈ \frac{1}{r_0^2} \\ \frac{1}{4}nU_0N_s \\ \gamma = \frac{F}{L} \\ [/tex] [h2]The Attempt at a Solution[/h2] I am stuck straight away on part A. I know the density of water (1000 kg/m^3) and the molecular weight of H2O is 18 but have no idea how these are supposed to help me calculate the average distance between the molecules. I am not looking for the answer but any hints on where to start would be very much appreciated. [/QUOTE]
