Answer:
1.39x10⁻⁶ mol
Explanation:
First we <u>convert the gallon of juice to liters</u>:
Then we <u>calculate the mass of antimony that would be in 3.785 L</u>, using the <em>given concentration</em>:
- 44.7 μg/L * 3.785 L = 169.2 μg
Then we <u>convert mass into moles</u>, using the <em>molecular mass</em>:
- 169.2 μg ÷ 121.76 μg/μmol = 1.39 μmol
Finally we <u>convert μmol into mol</u>:
- 1.39 μmol = 1.39x10⁻⁶ mol
Answer:
The amount of dissolved gases in the body. Have a good day! =)
Explanation:
Answer:
6,41 min
Explanation:
For the reaction:
A → products
kinetics first-order reaction law is:
ln[A] = ln[A]₀ -kt
Where [A] is concentration of reactant, [A]₀ is initital concentration of reactant, k is rate constant and t is time.
If the concentration of A is 6,25% you can assume:
[A] = 6,25; [A]₀= 100. Replacing:
ln(6,25) = ln(100) -7,20×10⁻³s⁻¹t
-2,7726 = -7,20×10⁻³s⁻¹t
385s = t
In minutes:
385s× = <em>6,41 min</em>
