To calculate the percentage purity of the sodium nitrite, we need the initial mass of the impure sodium nitrite that was used to prepare solution H. This value was not provided in the original problem statement or the image. In the previous answer, I demonstrated how to calculate the mass of pure sodium nitrite present in 1 dm³ of solution H, which was 2.895 g. To find the percentage purity, you would use the formula: Percentage purity = Mass of pure NaNO_2 in 1 dm^3Mass of impure NaNO_2 used to make 1 dm^3 × 100\% Since the "Mass of impure NaNO_2 used to make 1 dm³" is missing, the percentage purity cannot be calculated.
