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.

Part 2 of 2
H30+ = 0.040 M. Be sure your answer has the correct number of significant figures.

Part 1:
pH = -log(9.20x10^-2) = 1.04
Part 2:
pH = -log(0.040) = 1.40
