175.8 g NaCl to moles:
(175.8 g)/(58.44 g/mol) = 3.008 mol NaCl
Molarity = moles of solute/volume of solution in liters
(3.008 mol NaCl)/(1.5 L) = 2.0 M.
The molarity of this solution would be 2.0 M.
Answer:
S + 4 Cl2
Explanation:
Sulphur - S
1 mol of Sulphur = S
Chlorine = Cl2
4 moles of Chlorine = 4Cl2
4S + 2Cl2
Incorrect option
S + 4 Cl2
Correct option
S + 2Cl2
Incorrect option
S + Cl2
Incorrect option

combine to form water molecules.
a. True
b. False
The statement “When OH- and H+ ions are brought together,
they quickly combine to form water molecules” is true. The answer is letter A.
Answer:
Conc of Q at Equilibrium 2.1 × 10⁻³ mol/dm³
Ksp = 1.57 × 10⁻¹² mol/dm³
Explanation:
The Solubility of the Ionic compound is given by s
where s = 7 × 10⁻⁴ mol/dm³
solubility equation is given as follows
XQ₃(s) ⇄ X³⁺(aq) + 3Q⁻(aq)
s s 3s
let the concentration of each be s
The concentration of Q = 3s
⇒ [Q] = 3 × 7 × 10⁻⁴ mol/dm³
⇒ [Q] = 2.1 × 10⁻³ mol/dm³
hence,
Ksp = [X³⁺][Q⁻]³
Ksp = [s][3s]³
Ksp = [7 × 10⁻⁴ ][2.1 × 10⁻³]³
Ksp = 1.57 × 10⁻¹² mol/dm³
