Calculate the molarity of a solution that contains 12 grams of HCl in 350 mL of solution. What is the pH of the solution? 6. A 250 mL solution of H2SO4 has a strength of 0.2 M. The solution is diluted with water to the .750 L mark. What is the molarity of the solution so formed? Calculate the pH of the solution. Thanks in advance

What is the pH of the solution? Convert grams of HCl to moles of HCl Molarity = moles / volume in L pH = -log [H+] [H+] = [HCl]

What is the molarity of the solution so formed? Calculate the pH of the solution. Use dilution law M1V1=M2V2 Once you know Molarity ...get the concentration of H+ and then the pH
