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