What is 0.075 percent expressed in ppm?

Answer and explanation

Correct answer: 750 ppm

The conversion factor between percentage and ppm is 1% = 10,000 ppm. Therefore, multiply the percentage value by 10,000: 0.075 × 10,000 = 750 ppm. The same result follows by writing 0.075% as 0.00075 of the whole and multiplying by 1,000,000. Options B and C are smaller by factors of ten and one hundred; D is ten times too large.
