Answer:

i. No. of Gram Atoms = Given Mass/Atomic mass of that element in 1 mole

= 115/23

= 5

In the Given sample of 115 g Sodium, 5 g atoms are present.

ii. No. of Gram Atoms = Given Mass/Atomic mass of that element in 1 mole

= 5 = Given Mass/40

= 200 g = Given Mass

In the Given sample of 5 g atoms of Calcium, 200 g is present.

Hope this helps.
