(b) Whose container has more number of atoms?

AcademicChemistryNCERTClass 9

(a) Mass of sodium atoms carried by Krish
= (5 ×23) g = 115 g
(atomic weight of Na = 23)
Mass of carbon atom carried by Raunak = (5 ×12) g = 60g

(b) Both container has an equal number of atoms as equal moles of different atoms contain the same number of atoms.
