WebStep 3: Compute the mass of NaC2H3O2 produced from 2.8 moles of HC2H3O2. mass NaC2H3O2 = 2.8 mol HC2H3O2 × (1 mol NaC2H3O2 / 1 mol HC2H3O2) × (82.03 g NaC2H3O2 / 1 mol NaC2H3O2) mass NaC2H3O2 = 230 g. Step 4: Determine the limiting reagent. Since HC2H3O2 produces less amount of NaC2H3O2 than NaHCO3, HC2H3O2 is … WebpH salt basic Calculate the pH of a 0.46 M solution of LiC2H3O2 (Ka for HC2H3O2 = 1.8 x 10-5). Record your pH value to 2 decimal places. AI Recommended Answer: Step 1/11 1. First, we need to recognize that LiC2H3O2 is a salt formed from a strong base (LiOH) and a weak acid (HC2H3O2). When this salt is dissolved in water, it will undergo ...
