Question

Calculate the total number of electrons present in 1.6gm of CH4​

Answer 1

Answer:

MW of methane = 16 g/mole

So, no of moles of methane in 1.6 g = 1.6 /16 g/mole = 0.1

Since, in 1 mole methane there are 6.022 x 1023 molecules of methane,

so, in 0.1 mole there will be 0.1 x 6.022 x 1023 molecules of methane

In 1 methane molecule there are 10 electrons (6 + 4)

total electrons in 0.1 mole or 1.6 g = 10 x 0.1 x 6.022 x 1023

= 6.022 x 1023
