Raunak took 5 moles of carbon atoms in a container and Krish also took 5 moles of sodium atoms in another container of same weight. (a) Whose container is heavier? (b) Whose container has more number of atoms?
ScienceClass 9CBSEAnswered 27 Mar 2026
Answer
- Mass of sodium atoms carried by Krish = (5 ×23) g = 115 g Atomic weight of Na = 23
While mass of carbon atom carried by Raunak = (5 ×12) g = 60g
- Thus, Krish’s container has more number of atoms
