Explanation:
(6.1). The reaction equation will be as follows.
Assuming the value of 
as 
and let the solubility of each specie involved in this reaction is "s". The expression for will be as follows.
![K_{sp} = [Ba^{2+}][SO^{-}_{2}]](https://tex.z-dn.net/?f=K_%7Bsp%7D%20%3D%20%5BBa%5E%7B2%2B%7D%5D%5BSO%5E%7B-%7D_%7B2%7D%5D)
(Solids are nor considered)
= 
s = 
= 
= 
Therefore, solubility of barium sulfate in water is .
(6.2). As the molar mass of 
is 233.38 g/mol
Therefore, the solubility is g/L will be calculated as follows.
= 
Therefore, solubility of barium sulfate in grams per liter is .
Answer:
5.36 grams the mass in grams of zinc nitrate the chemist has added to the flask.
Explanation:
Moles of zinc nitrate = n
Volume of the solution = 135.0 mL = 0.1350 L
Molarity of the solution = 0.21 M
Mass of 0.02835 moles of zinc nitrate:
0.02835 mol × 189 g/mol = 5.358 g ≈ 5.36 g
5.36 grams the mass in grams of zinc nitrate the chemist has added to the flask.
