Calculate the [H3O

+] for 0.0077 M H2SO4.

Answer in units of M.

0.0154M

Explanation:

Let us write a balanced equation for the dissociation of H2SO4. This is illustrated below:

H2SO4 + 2H2O <=> 2H3O+ + SO4^2-

From the equation,

1mole of H2SO4 contained 2mol of H3O+

Therefore, 0.0077M of H2SO4 will contain = 0.0077M x2 = 0.0154M of H3O+.

The concentration of H3O+ is 0.0154M
