Astock solution contains a mixture of ~100 ppm chloride, fluoride, nitrite, bromide, nitrate and phosphate anions. in order to prepare 1 l of 100 ppm nitrite stock solution, you weigh out 150.0 mg of nano2. the actual concentration of nitrite would be:

Explanation:

The first step is to draw the ionization reaction of , so:

The molar ratio between and is 1:1

The next step is the calculation of the concentration. We have to remember that the formula of ppm is:

In this case we will have a mass of 150 mg and a volume of 1 L so:

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890
