a. Krish's container is heavier than Raunak's container.

b. Both container have the same number of atoms.

Explanation:

The molar mass of any element is equivalent to one mole of that substance.

weight of 1 mole of carbon atom is 12 g and weight of 1 mole of sodium atoms is 23 g.

So, the mass of 5 moles of carbon atoms

12 x 5 = 60 g

In this same way,

the mass of 5 moles of sodium atoms

23 x 5 = 115g

From this, we can say that Krishna’s container is heavier.

b. One mole of a carbon atom has 6.022 x 10^23 atoms and one mole of sodium also has 6.022 x 10^23 atoms.

So, 5 moles of carbon and sodium contains the same number atoms which are

5 x 6.022 x 10^23

= 3.011 x 10^24 atoms.
