As an expert in environmental science and chemistry, I can guide you through the process of calculating parts per million (ppm), which is a common measure of the concentration of a substance in a given mixture.
To calculate ppm, you need to know the mass of the substance of interest and the total mass of the mixture. The formula for ppm is:
**ppm = (mass of substance / total mass of mixture) × 1,000,000**
Here's a step-by-step guide:
1. Determine the mass of the substance you're interested in (in grams).
2. Determine the total mass of the mixture (in grams), which includes the substance of interest and everything else in the mixture.
3. Divide the mass of the substance by the total mass of the mixture.
4. Multiply the result by 1,000,000 to convert to ppm.
For example, if you have 5 grams of a contaminant in a 1,000,000-gram mixture, the calculation would be:
**ppm = (5 / 1,000,000) × 1,000,000 = 5 ppm**

PPM (Parts per million) is a measurement used by many customers to measure quality performance. To calculate: For example, if you had 25 pieces defective in a shipment of 1,000 pieces. 25/1000= .025 or 2.5% defective. . 025 X 1,000,000 = 25,000 PPM.
