Answer:
a mole of atoms is 6.02.10*" atoms.
Explanation:
How many atoms are in one mole of atoms?
A mole of a substance is defined as having around 6.02.104 units of that substance. This number is called Avogadro's number, and is denoted by NA. So we can say that NA6.02.1045 mol.Therefore, a mole of atoms is 6.02.10*" atoms.

Answer
Number of moles=n=
molecular weight
weight
1. 4 g He⇒

4
=1 mole
2. 46 g Na⇒
23
46
=2 moles
3. 0.4 g Ca⇒
40
0.4
=0.01 moles
4. 12 g He⇒

12
=3 moles
Number of moles ∝ number of atoms
Therefore 12 g He contains greatest number of atoms.
Hence, option D is correct.
