Question

In three moles of ethane (C2H6), calculate the number of molecules of ethane.

Answer 1

1 Mole consists of 6.022*10^23
so 3 moles will have *(6.022*10^23)
=18.066*10^23

Answer 2

"1 mole of C2H6  contains Avogadro’s no. 6.02×1023 molecules

∴ 3 moles of of C2H6  will contain ethane molecule = 3×6.02 ×1023= 18.06 ×1023 molecules."

Ethane has chemical formula C ₂H ₆ and it is an organic chemical compound. It is odorless and colorless gas at standard temperature and pressure present in air.
