Answer:

I think you mean how do you convert a mass of #15*g# of ethane to moles of ethane.

Explanation:

#"Moles of ethane"# #=# #(15.0*cancelg)/(30.07*cancelg*mol^-1)=??mol#.

And thus a mass of #15*g# of ethane represents #1/2# a mole of ethane. How many ethane molecules are there in such a molar quantity?
