Question

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. Whose container is heavier?

• A. Krish's container
• B. Raunak's container
• C. Both the containers are of same weight
• D. Cannot be determined

Answer 1

Answer: (A)

Krish's container

Since both the containers are of same mass so mass of atoms will decide which will be heavier.

Mass of 5 moles of sodium atoms in Krish's container $=(5\times 23)g=115g$

Mass of 5 moles of carbon atom in Raunak's container $=(5\times 12)g=60g$.

$\therefore$ Krish's container is heavier.

Hence the correct option is A.
