Question

Calculate the total number of electrons present in 1.6 g of CH4.?

Answer 1

Molecular mass of CH4(methane) = 12+4×1

= 16


➡Moles of CH4(Methane) = 1.6/16

=0.1


➡No. of electron in 1 molecule of CH4 = 6+4

= 10 electrons


➡Total no. of electrons = 0.1 × 6.022×1023 × 10

So, our final answer is :-

= 6.022×1023 electrons.
