Step-by-step explanation:
The value of [H+] can be calculated using the concentration of the HCl solution and the balanced chemical equation for the dissociation of HCl in water:
HCl (aq) + H2O (l) → H3O+ (aq) + Cl- (aq)
The concentration of HCl is 3.65 g / (36.5 g/mol) = 0.1 M
The concentration of H+ ions in the solution can be calculated using the concentration of HCl and the stoichiometry of the dissociation reaction:
[H+] = 0.1 M x (1 mol H+ / 1 mol HCl) = 0.1 M
To show that [OH-] is 1.00 x 10-12 M, we can use the relationship between [H+] and [OH-] in aqueous solutions, which is given by the ion product constant for water (Kw):
Kw = [H+] [OH-] = 1.00 x 10-14
Substituting the value of [H+] that we calculated above, we can solve for [OH-]:
[OH-] = Kw / [H+] = (1.00 x 10-14) / (0.1 M) = 1.00 x 10-12 M
Therefore, the concentration of OH- ions in the solution is 1.00 x 10-12 M.
