Step 1
In the given experiment the titration of borate with hydrochloric acid is being carried out at different temperatures. From the give data we are required to calculate the number of moles of borate titrated, concentration of borate at different temperature solubility product and the inverse of temperature.
Note: The number of moles of solution given are taken as millimoles instead of moles as it seems inappropriate to have 9.94 moles of in just of solution.
