In performing an experiment on freezing point depression, the solution was prepared by dissolving 2.25 g of salt in 20.00 mL distilled water (density = 0.997 g mL-1; Tf = 0 °C; kf = 1.86 °C m-1). We determined the freezing point of the solution to be -3.48 °C. We later found out that the salt we used was sodium chloride that was contaminated with potassium chloride. Calculate the mass of potassium nitrate present in the salt sample.

In performing an experiment on freezing point depression, the solution was prepared by dissolving
2.25 g of salt in 20.00 mL distilled water (density = 0.997 g mL-1; Tf = 0 °C; kf = 1.86 °C m-1). We determined the
freezing point of the solution to be -3.48 °C. We later found out that the salt we used was sodium chloride that was
contaminated with potassium chloride. Calculate the mass of potassium nitrate present in the salt sample.
