can you help me with this Calculate the pH from each H3O" concentration.

Part 1 of 2

H30 *= 9.20x10-2
M. Be sure your answer has the correct number of significant figures.

pH =

Part 2 of 2

H30+ = 0.040 M. Be sure your answer has the correct number of significant figures.

nH=

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.
