Answer:
The volume is 583.02 mL
Explanation:
Given that the density is:-
The mass,
The expression for the calculation of density is shown below as:-
Using the above expression to calculate the volume as:-
Applying the values to calculate the volume as:-
<u>The volume is 583.02 mL.</u>
(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=
6.022×10 ^23/4×52 =7.83×10 ^24 atoms
