Detailed Solution

 Carbon has an individual mass of 12 u, while hydrogen has a mass of 1 u. 

   C2 H6 is the chemical formula for ethane.

 Molecular mass of ethane 

= 2 X atomic mass of Carbon + 6 X atomic mass of hydrogen  

=2X 12 +  6 X 1

=   24+6 

= 30 u

 The molecular mass of ethane is 30 u.
