Silver ions can be found in some of the city water piped into homes. the average concentration of silver ions in city water is 0.028 ppm. (a) how many milligrams of silver ions would you ingest daily if you drank eight glasses (eight oz/glass) of city water daily?

A person ingests 0.053 mg of silver ions daily if they drank eight glasses of city water each day.

Further Explanation:

To solve the problem, the following equalities must be used:

0.028 ppm = 0.028 mg/L

1 glass = 8 oz

1 L = 33.8140 oz

The solution to this problem involves two steps:

STEP 1: To get the amount of silver ions in milligrams, first, determine how many liters of water are consumed daily if a person drinks 8 glasses per day. Here, the relationship below are needed:

1 L = 33.8140 oz

1 glass = 8 oz

Solving the equation gives the volume of city water ingested per day in L:

STEP 2: Now that the amount of water is known, calculate the amount of Ag+ present in it using the concentration given. Here, the relationship below is important:

0.028 ppm = 0.028 mg/L

Solving the equation gives the amount of silver ions per eight glasses of water:

Since the given 0.028 ppm only has 2 significant figures, the answer must also have 2 significant figures.

Therefore, the final answer is:
