In an experiment of HCl(g) is dissolved in water to make 100mL of an acidic solution. Assuming that the acid completely ionized, what is the pH of the solution?

For the first one Xg x 1mol/104.1g x 6.023E23molecules/1mol = 4.5E20 molecules Solve for x, [(104.1)(4.5E20)]/[(6.023E23)]= X Don't know how you would do that with out a calculator. For the second one, they don't give you the mass or moles of HCL? I dont see how you could solve that with out any concentrations, masses, or moles? Upvote 0 Downvote
