Question

if one mole of carbon atoms weight 12 gram, what is the mass ( in gram ) of 1 atom of carbon

Answer 1

Mass of one mole of carbon atom = 12g

1 mole of a carbon contains 6.022 X 1023 atoms

Hence, mass of 6.022 X 1023 Atoms of carbon = 12g

Mass of 1 atom of carbon

= 12/6.022 X 1023 = 1.993 X 10-23 g

Answer 2

hope it helps!
