in terms of parts per million (ppm) or parts per billion (ppb) because the amounts are so small. For example, a concentration of 1 ppm corresponds to 1 part material per 1 million parts of the gas, liquid or solid it is found in. In the case of ppb, the same relationship exists: 1 part material per 1 billion parts of a gas, liquid or solid. "ppm" value is the number of women you'd have if you have a million people and the same ratio of women/people. 16 25 1,000,000 = 640,000 ppm For a ppb, it's scaling up to a billion, or: 16 25 1,000,000,000 = 640,000,000 ppb This example isn't very useful for ppm or ppb, because we usually only use these quantities for very This chemistry video tutorial explains how to calculate the solution concentration in parts per million (ppm) and in parts per billion (ppb).My Website: htt This chemistry video tutorial explains how to convert ppm to ppb.
