(i) Number of moles of carbon atoms.
(ii) Number of moles of hydrogen atoms.
(iii) Number of molecules of ethane.​

Answer 1

Answer:

1 molecule of ethane contains 2 carbon atoms

so 3 moles of ethane contains 6 mole of carbon

Atoms.

1 molecule of ethane contains 18 mole of hydrogen atoms.

So 3 moles of ethane contains 18 mole of hydrogen atoms.

1 mole of ethane contains 6.023*10²³ molecules

Of ethane.

So 3 mole of ethane contains

3*6.023*10²³=18.069*10²³ molecules of ethane.
