Convert the mcl of antimony from milligrams per liter to parts per billion (ppb).

This is an incomplete question, here is a complete question.

According to the EPA, the maximum contaminant level (MCL) of antimony in drinking water is 0.0060 mg/L.

Convert the MCL of antimony from milligrams per liter to parts per billion (ppb).

Answer : The maximum contaminant level (MCL) of antimony in drinking water in parts per billion is, 6 ppb

Explanation :

ppb : It is defined as the mass of solute present in per 1000 million of total mass.

1 ppb =

As we know that:

1 milligrams per liter = 1000 parts per billion

or,

1 mg/L = 1000 ppb

As, 1 mg/L = 1000 ppb

So, 0.0060 mg/L =

                             = 6 ppb

Thus, the maximum contaminant level (MCL) of antimony in drinking water in parts per billion is, 6 ppb

yea hi

explanation:

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
