Suppose that a semiconductor plant uses 1,000,000 liters of city water per day to keep its production line of semiconductors runing. Also let's suppose that the water supplied to the plant contains 100 parts per million of Magnesium ions. Calculate the amount of Magnesium and water entering and leaving the filtration process. In order to do this problem, first we must understand what "parts per million"
means mathematically.Parts per million (ppm)is a description of the ratio of particles
in a solution to the total amount of solution by mass. A example of this is percentages.
5% is the same as saying 5 per hundred, or 5 parts per hundred.
