First, calculate pH using the pOH:

14 - pOH = pH --> pH = 14 - 5.5 = 9.5

[H+] = 10^-pH = 10^-9.5 = 3.2 x 10^-10 M ≈ 3 x 10^-10 M (The answer should technically only be one sig fig, since the pOH is given to only one decimal place).

E = ħc / λ
ħ = plancks constant = 6.626x10^-34 Js
c = speed of light = 2.999x10^8 m/s
λ = wavelength of light = 670.8x10^-9 m

E = (6.626x10^-34 Js) x (2.999x10^8 m/s) x (1 / 670.8x10^-9 m)
E = 2.962x10^-19 J

3x10^8 / (670.8 * 10^-9) =4.47x10^14 Hz

4.47x10^14 Hz multiplied by plank's constant = 2.9634x10^-19

[H3O+] = 2.9 x 10-10 M ph level

Zinaida [17]

Answer:

9.54

Explanation:

Fr the question given above, the following data were:

Concentration of hydronium ion [H3O⁺] = 2.9x10¯¹⁰ M

pH =?

The pH of the solution can be obtained as follow:

pH = –Log [H3O⁺]

pH = –Log 2.9x10¯¹⁰

pH = 9.54

Thus, the pH level of the solution is 9.54

Elodia [21]

Answer:Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some could tolerate. After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings. Unwilling to challenge the data openly, they erased the report from public view without a word to the authors. When the authors inquired, they received this letter:
