After Larry had taken Nexium for 4 weeks, the pH in his stomach was raised to 4.56. What is the [H3O+] in his stomach? Express the concentration to two significant figures and include the appropriate units.
Given:
pH = 4.56
use:
pH = -log [H3O+]
4.56 = -log [H3O+]
[H3O+] = 2.754*10^-5 M
Answer: 2.8*10^-5 M
