The correct answer to this question is this one:
<span>Pb(N<span>O3</span><span>)2</span>(aq)+<span>K2</span>S<span>O4</span>(aq)→PbS<span>O4</span>(s)+2KN<span>O3</span>(aq)
</span>Everything except the lead sulfate is soluble, so they all dissociate.
<span>P<span>b<span>2+</span></span>+2N<span>O−3</span>+2<span>K+</span>+S<span>O<span>2−</span>4</span>→PbS<span>O4</span>(s)+2<span>K+</span>+2N<span>O−3
</span></span>Cancel out stuff that appears on both sides, and your net ionic equation is
<span>P<span>b<span>2+</span></span>(aq)+S<span>O<span>2−</span>4</span>(aq)→PbS<span>O4</span>(s)</span>

Answer : The atomic mass of chlorine is, 36.723 amu
Explanation :
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
As we are given that,
Mass of 35-Cl isotope = 35 amu
Percentage abundance of 35-Cl isotope = 13.85 %
Fractional abundance of 35-Cl isotope = 0.1385
Mass of 37-Cl isotope = 37 amu
Percentage abundance of 37-Cl isotope = 86.15 %
Fractional abundance of 37-Cl isotope = 0.8615
Now put all the given values in above formula, we get:
Therefore, the atomic mass of chlorine is, 36.723 amu
