How many parts per million (PPM) does 1.25% Carbon Dioxide equal?

How many parts per million (PPM) does 1.25% Carbon Dioxide equal?

• A. 12500 PPM
• B. 5000 PPM
• C. 2500 PPM
• D. 15000 PPM

Answer: (A)

To convert a percentage to parts per million (PPM), you multiply the percentage by 10,000. This conversion is based on the understanding that 1% is equivalent to 10,000 parts per million because 1% is 1 part per 100 parts, and when scaled to a million, it becomes 10,000 parts per million. Here, if you take 1.25% and multiply it by 10,000, the calculation would be: 1.25% * 10,000 PPM = 12,500 PPM. Thus, 1.25% of Carbon Dioxide corresponds to 12,500 PPM, making it the correct answer in this scenario.
