Using the following information, calculate the number of moles of HCl, Moles of Borate, Concentration of Borate, Ksp, Average Ksp, ΔG (kJ/mol), ΔH (kJ/mol), and ΔS (J/mol*K):

Na2B4O7 • 10H2O(s) -><- 2Na+(aq) + B4O5(OH)42−(aq) + 8H2O(l)

Titration: B4O5(OH)42-(aq) + 2HCl(aq) + 3H2O(l) → 4 B(OH)3(aq) + 2 Cl− (aq)

Molar Mass of B: 10.81g/mol, Molar Mass of O: 16.00g/mol, Molar Mass of H: 1.008g/mol, Molar Mass of Cl: 35.45g/mol

K = [Na+]2 [B4O5(OH)42-]

Ksp = 4 [B4O5(OH)42-]3

ΔG = −RT ln Ksp

ΔG = ΔH – TΔS

−RT ln Ksp = = ΔH – TΔS

a)Titration 1: Temperature: 28.0 degrees C, Concentration of HCl: 0.251 M, Volume of Borax solution (mL): 5.00, Volume of HCl titrated: 2.00 mL

Please do not post the lab that this question comes from because it is hard for me to understand. Please show each individual step and use units along the way to the answer. Thanks!

I need help solving for heat flow, moles of water produced and enthalpy change with the data. Please, thanks.
