Doc Jill wants to determine the Ao of a weak acid she isolated called Yurdaughteric acid (HYd). She prepared a solution of the weak acid by diluting 3.5 mL of 0.10 M HYd with 13.5 mL of water. Upon measuring the conductivity of the solution and a blank, she obtained 192.0 µS/cm and 4.0 uS/cm, respectively. She also measured the pH of the solution and got a pH of 3.12. Help her find the following: 1. Concentration of the weak acid (HYd) after dilution 2. Corrected conductivity 3. Molar conductivity of the solution 4. Equilibrium concentration of H3O*, and Yd

Doc Jill wants to determine the Ao of a weak acid she isolated called Yurdaughteric acid (HYd). She prepared a
solution of the weak acid by diluting 3.5 mL of 0.10 M HYd with 13.5 mL of water. Upon measuring the
conductivity of the solution and a blank, she obtained 192.0 µS/cm and 4.0 µS/cm, respectively. She also
measured the pH of the solution and got a pH of 3.12. Help her find the following:
1. Concentration of the weak acid (HYd) after dilution
2. Corrected conductivity
3. Molar conductivity of the solution
4. Equilibrium concentration of H3O*, and Yd
