(b) Potassium nitrate was synthesized in an experiment using 10 mL of nitric acid and excess potassium hydroxide. The mass data obtained from the experiment is shown in Table 1 below. Given that the percentage yield of potassium nitrate was 88.3 %, calculate the concentration (% m/v) of the nitric acid used in the experiment. Table 1: Mass data for the synthesis of potassium nitrate from nitric acid and potassium hydroxide Mass of clock glass and crystallized potassium nitrate/ g 45.55 Mass of empty clock glass/ g 39.18
