The answer to your question should be genes.
<span>Gallium-72 that is what i got when i did the math for it</span>
Answer:
Answers are in the explanation
Explanation:
Ksp of CdF₂ is:
CdF₂(s) ⇄ Cd²⁺(aq) + 2F⁻(aq)
Ksp = 6.44x10⁻³ = [Cd²⁺] [F⁻]²
When an excess of solid is present, the solution is saturated, the molarity of Cd²⁺ is X and F⁻ 2X:
6.44x10⁻³ = [X] [2X]²
6.44x10⁻³ = 4X³
X = 0.1172M
<h3>[F⁻] = 0.2344M</h3><h3 />
Ksp of LiF is:
LiF(s) ⇄ Li⁺(aq) + F⁻(aq)
Ksp = 1.84x10⁻³ = [Li⁺] [F⁻]
When an excess of solid is present, the solution is saturated, the molarity of Li⁺ and F⁻ is XX:
1.84x10⁻³ = [X] [X]
1.84x10⁻³ = X²
X = 0.0429
<h3>[F⁻] = 0.0429M</h3><h3 /><h3>The solution of CdF₂ has the higher fluoride ion concentration</h3>
Answer:
3.4 moles of silver * 107.868 grams of silver/1 mole of silver = 370 grams of silver.
Explanation:
According to the NYS Reference Table, one mole of silver equates to 107.868 grams. Therefore, if you want to convert from moles to grams, the mole unit should be on the bottom, since it is the unit being cancelled out. Above the mole unit should be the gram unit, since it is the unit you want to convert to. Once you do the math with significant figures, the solution turns out to be 370 grams of silver.
I honestly do not know the answer. sorry
