A chemist dissоlves 0.105 g оf pоtаssium nitrаte (KNO₃) in 175.0 mL of wаter. What is the concentration of the solution in parts per million (ppm)? Assume the density of the solution is approximately 1.00 g/mL, since the amount of potassium nitrate added is very small and does not significantly change the total volume of the solution.
