A 1.00 l sample of water contains 0.0056 g of nh2- ions. determine the concentration of nh2- ions in ppm if the density of the solution is 1.00 g/ml.

Sagot :

In ppm the concentration of NH2- ions is 5.6 ppm.

We have 1 L sample of water contains 0.0056 g of NH2- ions.

We have to determine the concentration of NH2- ions in ppm.

What is PPM ?

PPM is a term used in chemistry to denote a very, very low concentration of a solution.

According to the question -

Mass of the aqueous solution of NH2- ions → density x volume →

1 L x 1000 mL x 1 g/mL = 1000g

Now, the ratio of chloride ion mass to the solution mass will give the concentration of NH2- ions →

[tex]$c= \frac{0.0056}{1000}[/tex]

Now, in order to express the concentration in parts per million -

[tex]$c= \frac{0.0056}{0.001 \times 10^{6} } = \frac{5.6}{10^{6} }[/tex]

Now -

c = 5.6 g of NH2- ions per 1 million grams of solution which is equal to concentration in ppm.

Hence, in ppm the concentration of NH2- ions is 5.6 ppm.
