Answer: The correct answer is (1).
Explanation:
Concentration of the solute in 1000 g of solution: 5 parts per million
1 part per million = 1 milligram/Liter
Then , 5 parts per million = 5 mg/liter
This means that 5 milligrams of solute is present in 1 liter solution.
1 gram = 1000 milligrams
Then 5 milligram = [tex]5\times \frac{1}{1000} g[/tex] = 0.005 grams
Hence, 0.005 grams is the total mass of solute in 1000 grams of a solution having a concentration of 5 parts per million.
Parts per million (ppm) is how many parts a certain molecule or compound makes up within the one million parts of the whole solution.
Concentration of the solute in 1000 g of solution: 5 parts per million
1 part per million = 1 milligram/Liter
Then , 5 parts per million = 5 mg/liter
This means that 5 milligrams of solute is present in 1 liter solution.
1 gram = 1000 milligrams
Then 5 milligram = 5 X[tex]\frac{1}{1000g}[/tex] = 0.005 grams.
Hence, 0.005 grams is the total mass of solute in 1000 grams of a solution having a concentration of 5 parts per million.
