0.01 percent impurity is equal to how many ppm?
Answer and explanation
Correct answer: 100 ppm
The governing unit conversion is 1% = 10,000 ppm, because one percent is one part per hundred while one ppm is one part per million. Therefore, 0.01% × 10,000 = 100 ppm. Option A is correct. Equivalently, 0.01/100 × 1,000,000 = 100. The other choices result from shifting the decimal by one or more places incorrectly.
