How to calculate molarity of buffer solution
Web30 mrt. 2024 · The first solution contains 0.02 × 100 g = 2 g of salt, and the second solution contains 0.10 × 150 g = 15 g of salt. So in total you have 2 g + 15 g = 17 g of salt and 100 g + 150 g = 250 g of solution. This gives a 17 g / 250 g = 0.068 or 6.8 percent concentration final solution. Cite this Article. WebProblem #14: Calculate the pH after 0.020 mol of HCl is added to 1.00 L of 0.10 M NaC 3 H 5 O 2.K a = 1.3 x 10-5.. Solution: 1) After adding the HCl, the solution will contain some propanoic acid and some sodium propionate (the NaC 3 H 5 O 2).The solution is a buffer and we will use the Henderson-Hasselbalch equation at the end to get the pH.

For the example, Solution 1 is 0.05 L and Solution 2 is 0.120 L. The final volume = 0.05 L + 0.120L = 0.170 L. Calculate the final molarity of the mixed solution using the equation molarity = moles ÷ liter. For the example, the final molarity is 0.0135 moles ÷ 0.170 liters = 0.079 M.
