Answer:
Solubility = [SO₄²⁻]
Explanation:
Solubility of Ag₂SO₄ can be understood seen its Ksp equilibrium:
Ag₂SO₄(s) ⇄ SO₄²⁻ + 2Ag⁺
<em>Where 1 mole of silver sulfate dissolves producing 1 mole of sulfate ion and 2 moles of silver ion.</em>
Solubility is defined as: "the amount of solid that can be dissolved per liter of solution".
In the dissolution process, the moles of Ag₂SO₄ dissolved are equal to moles of SO₄²⁻.
That means:
<h3>Solubility = [SO₄²⁻]</h3>
Answer: C autotrphic herbivore and eukaryotic
Answer:
2.275x10⁶g of CN⁻¹ were dissolved in the sample
Explanation:
Molarity is defined as the ratio between moles of solute and liters of solution.
If a CN⁻¹ solution has a concentration of 25mM, there are 0.025 moles of CN⁻¹ per liter of solution.
If the sample has a colume of 3.5x10⁶L, moles of CN⁻¹ are:
3.5x10⁶L × (0.025moles / L) = <em>8.75x10⁴ moles of CN⁻¹ in the sample of water.</em>
In grams (As molar mass of CN⁻¹ is 26g/mol):
8.75x10⁴ moles CN⁻¹ × (26g / mol) = <em>2.275x10⁶g of CN⁻¹ were dissolved in the sample</em>
