Answer:
2.9x10^–8 M
Explanation:
Data obtained from the question include the following:
pH = 7.54
Concentration of hydronium ion, [H3O+] =.?
The Concentration of hydronium ion, [H3O+] can be obtain as follow:
pH = - log [H3O+]
7.54 = - log [H3O+]
- 7.54 = log [H3O+]
[H3O+] = Antilog (-7.54)
[H3O+] = 2.9x10^–8 M
Therefore, The concentration of hydronium ion, [H3O+] is 2.9x10^–8 M
