Answer:
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
