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.

  1. Whose container is heavier?
  2. Whose container has more number of atoms?

Answer:

  1. Mass of sodium atoms carried by Krish = (5 X 23) g = 115 g
    Mass of carbon atoms carried by Raunak = (5 x 12) g = 60 g
    Thus, Krish’s container is heavier.
  2. Both the bags have same number of atoms as they have same number of moles of atoms.
