WebAug 29, 2024 · Molarity is one of the most common units of concentration. Molarity is the number of moles of a substance per unit volume. Question a. State the concentration, in moles per liter, of each ion in 1.0 mol Al (NO 3) 3. b. State the concentration, in moles per liter, of each ion in 0.20 mol K 2 CrO 4 . Solution Part a. WebSo the moles of the acetate anion are equal to 0.270, and the moles of a acidic acid is equal to 0.230. And when we solve for the pH, we find the pH of the solution is equal to 4.81. So buffer one started at a pH of 4.74, and after the addition of the hydroxide anions, the pH rose a little bit to 4.81, however, that's a relatively small change ...
