According to the epa, the maximum contaminant level (mcl) of antimony in drinking water is 0.0060 mg/l. a farmer recently dug a new well for his property. he sends a 12.0 ml 12.0 ml sample of the well water to the epa to be tested for the presence of antimony. what is the maximum amount of sb sb (in μg μg ) that can be present in this 12.0 ml 12.0 ml sample based on its mcl?

The maximum amount of Sb that can be present in this 12 mL sample based on MCL, is 0.072 μg

Explanation:

The maximum contaminant level according to EPA is given as:

Max Level = 0.006 mg/L

Max Level = (0.006 mg/L)(1 L/1000 mL)

Max Level = 0.006 x 10^-3 mg/mL

Now, the sample size is 12 mL. Hence the maximum amount of Antimony (Sb) can be ount out by the use of maximum Contaminant Level.

Max. Amount = (Max. Level)(Sample Size)

Max. Amount = (0.006 x 10^-3 mg/mL) (12 mL)

Max. Amount = 0.072 x 10^-3 mg

Max. Amount = 0.072 μg

false

because it does not have the potential to be entirely used up
