What is the molecular weight of a substance, each molecule of which contains `9` carbon atoms, `13` hydrogen atoms and `2.33 xx 10^(-23) g` of other component ? |

Answer» The molecule has `C, H` and other component. w.t of `9 C` atoms `=12xx9 =108` amu w.t of `13 H` atoms `=13xx1= 13` amu w.t of other component `=(2.33xx10^(-23))/(1.66xx10^(-24))= 14.04` amu `:.` Total weight of one molecule `= 108+13+14.04` `=135.04` amu `:.` Mol.wt. of substance `= 135.04` |
