Calculate the solubility of silver oxalate, ag2c2o4, in pure water. ksp = 1.0 × 10-11
aksik [14]
Answer is: the solubility of silver oxalate is <span>a. 1.4 × 10-4 m.
</span>

<span>Chemical reaction (dissociation) of silver oxalate in water: 
Ag</span>₂C₂O₄(s) → 2Ag⁺(aq) + C₂O₄²⁻<span>(aq).
Ksp(Ag</span>₂C₂O₄) = [Ag⁺]²·[C₂O₄²⁻<span>].
[C</span>₂O₄²⁻] = x; solubility of oxalate ion.

[Ag⁺] = 2[C₂O₄²⁻<span>] = 2x
1.0·10</span>⁻¹¹ = (2x)² · x = 4x³.

x = ∛1.0·10⁻¹¹ ÷ 4.

x = 1.4·10⁻⁴ M.

how many liters of radon gas would be in 3.43 moles at standard temperature and pressure (273K and 100 kPa)?
bagirrra123 [75]

Answer:

V = 0.0007678398L

Explanation:

Given parameters:

Number of moles of gas = 3.43moles

Temperature = 273k

pressure = 100kPa = 100000Pa

Unknown:

Volume of gas = ?

Solution

The gas is at standard temperature and pressure, this implies we can use the ideal gas equation to solve for the unknown.

Mathematically, the law is expressed as:

                               PV = nRT

The unknown here is the Volume, V. We know the other parameters.

       P = pressure on the gas

      n = number of moles

       R = gas constant=0.082

       T = temperature

now, we have to make V the subject of the expression:

                   V = \frac{nRT}{P}

                   V = \frac{3.43 x 0.082 x 273}{100000}

                   V = 0.0007678398L
