can you help me with this write the correct significant figure and standard form Calculate the pH from each H3O" concentration. Part 1 of 2 H3O+7 pH = -4 =3.9x10 M. Be sure your answer has the correct number of significant figures.information.
Part 2 of 2
H3 0+ = 0.0000045 M. Be sure your answer has the correct number of significant figures.
Part 1:
The correct significant figures for the H3O+ concentration of 3.9x10^-4 M should be 2 significant figures, so the pH should be 4.
Part 2:
The correct significant figures for the H3O+ concentration of 0.0000045 M should be 2 significant figures, so the pH should be 5.
