35 ppm is equivalent to approximately what percent?

• A. 0.00035%
• B. 0.0035%
• C. 0.035%
• D. 0.35%

Answer: (B)

Converting parts per million to percent uses the fact that 1% equals 10,000 ppm. So to get percent from ppm, divide by 10,000. For 35 ppm: 35 ÷ 10,000 = 0.0035%. This is the same as multiplying by 0.0001. The other options correspond to different ppm values: 3.5 ppm, 350 ppm, or 3500 ppm, which would be 0.00035%, 0.035%, or 0.35%, respectively.
