An unknown 36% v/v monohydroxide reagent has a density of 1.8 g/mL. Zeus wanted to determine the identity of this base, so he transferred a 90.916-mL aliquot of the base to a 1.0 L volumetric flask and diluted it up to mark. He then titrated the base solution and found out that its concentration is 1.0 M. a. What is the molarity of the base solution after dilution? b. If this 1.00M solution is used in the analysis of PLA (Polylactic Acid) plastics for lactic acid (H2Lactate) titration, what is its concentration in titer mg LA/mL titrant? (Lactic Acid: 90.08 g/mol) c. What is the molarity of the unknown monohydroxide reagent? d. What is the molar mass of the unknown monohydroxide reagent?(Density of H2O = 0.99707 g/mL) Hint: Mass of solution = mass of solvent + mass of solute e. What is the identity of the unknown monohydroxide reagent?
