Question

Find moles of electrons present in 64g of Ch4
(1)64
(2)40
(3)24
(4)16

Answer 1

Number of moles in 64 grams = 64/16 = 4 moles

1 mole of CH4 contains →6 + 4 = "10 moles of electrons"

So, 4 moles of CH4 contains →4 x 10 = "40 moles of electrons"

Thus 64 grams of CH4 contains 40 moles of electrons.
