Part 1:
To calculate the pH from the H3O+ concentration of 9.20 x 10^-2 M, you can use the formula: pH = -log[H3O+].
Plug in the given H3O+ concentration:
pH = -log(9.20 x 10^-2) = -(-1.036) = 1.036
Therefore, the pH is 1.04.
Part 2:
To calculate the pH from the H3O+ concentration of 0.040 M, you can use the formula: pH = -log[H3O+].
Plug in the given H3O+ concentration:
pH = -log(0.040) = -(-1.397) = 1.397
Therefore, the pH is 1.40.
