Answer:
unique
sweet
loveable
friendly (hope so)
and cute
Explanation:
(i) 1 mole of Ar =6.022×10
23
atoms of Ar
52 mol of Ar=52×6.022×10
23
atoms of Ar
=3.131×10
25
atoms of Ar
(ii) Atomic mass of He = 4amu
Or
4amu is the mass of He atoms = 1
Therefore 52 amu is the mass of He atoms=0.25×52=13 atoms of He
(iii) Gram atomic mass of He = 4g
Or
4g of He contains =6.022×10
23
atoms
Therefore 52 g of He contains=
4×52
6.022×10
23
=7.83×10
24
atoms
