Question

A sample of tap water contains 75 ppm aqueous FeCl3. How many particles of tap water would there be for every 75 particles of FeCl3? Group of answer choices 1,000 100,000 1,000,000 1000 10,000

Answer 1

1,000,000 particles of tap water would be for every 75 particles of FeCl3

Step-by-step explanation:

sample of tap water contains 75 ppm aqueous FeCl3.

i.e sample of water is 75 particular per million aqueous FeCl3

Sample of water = 75/1000000 particular of FeCl3

x particular of water = 75 particular of FeCl3

To find the value of x, we cross multiply

Therefore we have:

75 = 75/1,000,000X

X = 75 / (75/1000000)

X = 75 x 1000000/75

X = 1,000,000.

1,000,000 particles of tap water would be for every 75 particles of FeCl3
