Heya

Atomic weight of methane is 12+4(1)=16g

16g make up one.mole

No.of MOLES of methane in 1.6g = 1.6/16 = 0.1 moles

In one mole of methane 6.022×10²³number of molevules are present.

In 0.1 mole 6.022×10²³×0.1 = 6.022×10²² molecules of methane

In one MOLECULE, 10 electrons are present.

In 0.1 mole NUMBER of electrons present​ are 6.022×10²²×10 = 6.022×10²³

Hope it HELPS! ^_^
