1 mole of methane(CH_4) contains 5 atoms.
Carbon has 12 electrons, hydrogen has 1 electron. So totally it contains 16 electrons
16g consists of 1 mole(6.023×10^23) atoms. Thus 0.16 contains 6.023×10^21 atoms.
0.16g of methane contains 16× 6.023×10^21 electrons.
=96.368×10^21 electrons.

Answer:
Explanation:
CH4 contains 5 atoms
1 mole =16 g
0.01 mole=0.16g
ie number of electrons=0.16*6.022*10^23
