To determine the number of grams of potassium hydroxide, we need to know what is the units of parts per million and what it means. Then, we can multiply the grams of solution to obtain the grams KOH. Parts per million (ppm) means that there is 1 mass unit of solute per 1 million mass units of solution. Therefore,
300 ppm = 300 g KOH / 1000000 g solution
mass KOH = 300 g KOH / 1000000 g solution (1000 g solution)
mass KOH = 0.3 g KOH
