Question

the no. of electrons in 1.6g of CH4 is approximately
(1) 25*10²⁴
(2)1.5*10²⁴
(3)6*10²³
(4)3.0*10²⁴
​

Answer 1

6*10^23

means option c is the correct answer

hope it helps you ☺️

Answer 2

Answer:

(3)6*10²³

1 mole= 6.023× 10²³

CH4 moles= 1.6/16= 0.1 moles

So total atoms = 1.0× 6.023× 10²³

= 6.023 × 10²⁴ atoms

one CH4 molecule = 10 electrons

(6( Carbon) +4 (Hydrogen))

Total electron in 0.1 mole

= 10× 0.1× 6.023×10²³

= 6.023× 10²³
