Answer to Question #112958 in General Chemistry for Nicolas

Question

If a 65 mL solution of HCl has a concentration of 0.326 M, what is its pH? Also, how many
grams of HCl are in the solution?

Answer 1

Solution:

pH = - lg[HCl] = 0.487

m(HCl) = n(HCl)*M(HCl) = C(HCl)*V(HCl)*M(HCl) = 0.326 M*0.065L*36.46g/mol = 0.77 g
