Take the given 2.00 moles of hydrogen then divide it by 1 mole of hydrogen. Second you want to multiply the answer by 22.4L. Giving you an answer of 44.8L of hydrogen
Answer:
The answer is growth rate
Explanation:
it will help you
Answer:
n₂ = 2.55 mol
Explanation:
Given data:
Initial number of moles = 0.758 mol
Initial volume = 80.6 L
Final volume = 270.9 L
Final number of moles = ?
Solution:
Formula:
V₁/n₁ = V₂/n₂
V₁ = Initial volume
n₁ = initial number of moles
V₂ = Final volume
n₂ = Final number of moles
now we will put the values in formula.
V₁/n₁ = V₂/n₂
80.6 L / 0.758 mol = 270.9 L/ n₂
n₂ = 270.9 L× 0.758 mol / 80.6 L
n₂ = 205.34 L.mol /80.6 L
n₂ = 2.55 mol
Answer:
The solution has a pH value of 9.3.
Explanation:
To solve this problem, we can first determine the H+ ion concentration and then use this value to calculate the pH. To find the H+ ion concentration from the OH- ion concentration, we should use Kw, which we know has a value of 1 * 10^(-14).
We can then use the following formula to solve for [H+]:
Kw = [H+][OH-]
10^(-14) = (2.02 * 10^(-5)) * [H+]
[H+] = 4.950495 * 10^(-10)
Now, we can find the pH using the formula pH = -log[H+].
pH = - log[H+]
pH = - log(4.950495 * 10^(-10))
pH = 9.3
Therefore, the correct answer is that the pH of the solution is 9.3. Note that an alternative way to solve the problem is to find the pOH from the OH- ion concentration and use the resulting value to determine the pH that way instead.
Hope this helps!
