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?

Answers (1)

Solution.

(a) Mass of sodium atoms carried by Krish = (5 \times 23) g = 115 g
While mass of carbon atom carried by Raunak = (5 \times12) g = 60g
Thus, Krish’s container is heavy.
(b) As the two bags have the same number of moles of atoms, both the bags will have the same number of atoms.
