Given mass/molar mass = 64

Molar mass of methane = 16

Therefore,

No. of moles of methane = 64/16 = 4.

So, there are 4 moles of methane in 64amu of ch4.

Since, Avogadro's number= 6.022 * 10^23 i.e number of units in one mole of any substance)

We can also write 4* 6.022 * 10^23 molecules of methane [ one mole has weight as molecular weight in gm] .

Since each molecule has 10e, we can also write

10 * 4 * 6.022 *10^23 e in 64 gm of methane.
