1 mole=6.023*10^23 molecules
1 molecule=1/(6.023*10^23) moles
=>1*10^23 molecules=10^23/(6.023*10^23) moles
                                   =0.166 moles
=>mass of 1*10^23 molecules of methane=0.166*16    (wt.=no. of moles*G.M.W)
                                                                    =2.656 gm

Mass of 6.023*10²³ molecules=16
mass of 1*10²³ molecules=16/6.023
                                     =2.656
