Question

Mole 5 mole of an carbon atom and 5 mole of sodium atom is contained at same weight of container which contain is heavier container has more number of atom

Answer 1

Sodium atom containing container is more heavy as mass of a sodium atom is more than a carbon atom.
However since you had difficulty typing question and wanted to ask if both have same weight then which had more answers then here's your answer again:
Carbon atoms would be more than sodium atoms as carbon atoms have less weight than sodium atoms so more carbon atoms are needed for few sodium atoms.
