Answer:
The answer to the question is
The solution contains 4.73 % by mass of NaCl
Explanation:
To solve this we list out the variables thus
The Molarity of NaCl = 0.850 M,
Density of solution = 1.05 g/mL
Molar mass of NaCl = 58.44 g/mol
Therefore mass of NaCl in he solution = (58.44 g/mol) × (0.850 M) = 49.674 g of NaCl
However the density = 1.05 g/mL or 1050 g/L
Therefore the mass percent of NaCl in 1 liter of solution or 1050 g of solution = (49.674/1050) × 100 = 4.73 %
The concentration of NaCl in mass percent = 4.73 %

The Ksp of AgOH will be "1.98×10^-8"
According to the question,
The chemical reaction is:
AgOH + HCl → AgCL(s) + H2O
As we know the relation,
C₁V₁ = C2V2
(AgOH) (HCI)
By substituting the values, we get
C₁ x 250 mL = 0.0136 × 2.60 mL
C1 = 0.0136×2.60/250 = 0.000141
Now,
AgOH = Ag + OH
AgOH = Ag + OH (s) (s)
hence, The Ksp will be: (s)^2 = (0.000141)² =
1.98 x 10^-8
The Ksp of AgOH will be 1.98×10^-8
