1.	In three moles of ethane (C_(2)H_(6)) calculate the following:(i) Number of moles of carbon atoms.(ii) Number of moles of hydrogen atoms.(iii) Number of molecules of ethane.
Answer» SOLUTION :(i) 1 mole of `C_(2)H_(6)` contains 2 moles of Carbon atoms. `:.` 3 moles of `C_(2)H_(6)` will have 6 moles of Carbon atoms. (ii) 1 mole of `C_(2)H_(6)` contains 6 moles of Hydrogen atoms. `:.` 3 moles of `C_(2)H_(6)` will have 18 moles of Hydrogen atoms. (III) 1 mole of `C_(2)H_(6)` contains `6.023xx10^(23)` NUMBER of molecules. `:.` 3 moles of `C_(2)H_(6)` will contain `3xx6.023xx10^(23)` molecules.
