Sonny Hendrix · Answer 1

From the Avogadro's constant 1 mole = 6.022 * 10^23 atoms

1g of Carbon-12 contains = 1/12 = 0.083 moles

Therefore; 0.083 moles * 6.022*10^23

= 4.9983 * 10^22 atoms

1g of Carbon-13 contains = 1/13 = 0.077 moles

= 4.6370 * 10^22 atoms

Therefore; Carbon-12 has more atoms than Carbon-13
