1.6 gram of Methane means 0.1 mole of it.
1 mole of Methane has 5 moles of electrons as there are five atoms in it. Hans 0.1 mole of Methane contains 0.5 mole of electrons which concludes that it has 3.011 into 10 raise to the power 23 electrons.

Each molecule contains 1 carbon (6 electrons) & 4 hydrogens (4 electrons)

Thus, 1 molecule of methane has a total of 10 electrons. 

1mole of methane (16 grams) contains Avogadro number of molecules.

0.1moles of methane( 1.6grams) contains '0.1 x Avogadro number' of molecules.

Thus 0.1 mole of CH₄ contains "10 x 0.1 x Avogadro number" of electrons.
                    
                                               → Avogadro number of electrons


Therefore 1.6 grams of methane contains 6.022 x 10²³ electrons.
