Answer 2

Gram-molecular mass of methane =12+4=16g

Number of moles in 1.6g of methane = 16

1.6

=0.1

Number of molecules of methane in 0.1 mole=0.1×6.02×10

23

=6.02×10

22

One molecule of methane has 6+4=10 electrons

So,

6.02×10

23

molecules of methane have 10×6.02×10

22

=6.022×10

23

electrons
