Answer:
36.693
Explanation:
From the question given, the following were obtained:
Let 35Cl be isotope A and 37Cl be isotope
For isotope A (35Cl),
Mass number = 34.9700
Abundance = 13.85 %
For isotope B (37Cl),
Mass number = 36.9700
Abundance = 86.15 %
Atomic mass =
[( Mass of AxAbundance A)/100] + [(Mass of BxAbundance B)/100]
[(34.97x13.85)/100] + [(36.97x86.15)/100]
= 36.693

Correct Answer: <u>Option B i.e. 0.82 M
</u>
Reason:
<em>Given:</em> number of moles of BaCl2 = 0.98, Volume of solution = 1.2 l
Molarity of solution = </span>
<span>
= </span>
<span>
= 0.82 M
Thus, molarity of the solution is 0.82 M</span>
