can you help me with this

Calculate the pH from each H3O" concentration.

Part 1 of 2

[H30+ = 4.5 x 10^-4

pH =

M. Be sure your answer has the correct number of significant figures.

To calculate the pH from the H3O+ concentration, you can use the formula: pH = -log[H3O+]

Given [H3O+] = 4.5 x 10^-4, plug this into the formula:

pH = -log(4.5 x 10^-4)
pH = -log(4.5) + 4 = 3.35

Therefore, the pH is 3.35. Make sure to keep the correct number of significant figures in your final answer.
