rinking water suggest an upper limit of 250 mg/L for chloride ion. If 1.03×104 liters of water in a storage tank contains 1.40 grams of Cl-, what is the contaminant level in ppm? in ppb? Is this level acceptable based on EPA guidelines?

This water has a level acceptable, 0.1359ppm and 135.9ppb.

Explanation:

1.40g of Cl⁻ are:

1.40g Cl⁻ × (1000mg / 1g) = 1400mg Cl⁻

In 1.03x10⁴L:

1400mg / 1.03x10⁴L = 0.1359mg/L.

As the upper limit of Cl⁻ in water is 250mg/L, this water has a level acceptable

ppm are the ratio between mg of solute and liters of solution, that means the tank contains 0.1359mg/L = 0.1359ppm

ppb, parts per billion are 1000 times ppm, thus, parts per billion of the storage tank are:

0.1359ppm × 1000 = 135.9ppb

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

the answer is c i took the test
