(ii) 1 mole of C2H6 contains 6 moles of Hydrogen atoms

∴ 3 moles of of C2H6 will contain 18 moles of Hydrogen atoms

(iii) 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.

Hope This Will Help you ☺
