A 0.7026 g sample of an unknown acid needs 40.96 mL of0.1158 M NaOH for neutralization to a phenolphthalein end point. There is 1.22 mL of 0.1036 M HCl used for back titration.
1. Determine how many moles of OH are used and how many moles of H from HCl?
2. How can calculate the moles of H are there in the solid acid?
3. Determine the molar mass of the unknown acid?
