Final answer:
The [H₃O⁺] of a solution with a given pH can be calculated using the formula [H₃O⁺] = 10^(-pH). For pH values of 8.37 and 1.55, the [H₃O⁺] is approximately 2.01 × 10^(-9) M and 2.81 × 10^(-2) M, respectively.
Step-by-step explanation:
The [H₃O⁺] of a solution can be calculated using the pH value. The pH is a measure of the concentration of hydronium ions in a solution.
The formula to calculate [H₃O⁺] from pH is:
[H₃O⁺] = 10^(-pH)
Let's calculate the [H₃O⁺] for the given pH values:
- For pH = 8.37, [H₃O⁺] = 10^(-8.37) = 2.01 × 10^(-9) M.
- For pH = 1.55, [H₃O⁺] = 10^(-1.55) = 2.81 × 10^(-2) M.
Therefore, the [H₃O⁺] for the given solutions are approximately 2.01 × 10^(-9) M and 2.81 × 10^(-2) M, respectively.
