A sample from a local stream is found to have 3.0 ppm nitrates (in the form of sodium nitrate). How many grams of sodium nitrate

maw [93]

Answer:

0.01028 grams of sodium nitrate would there be in 2.5 L of the stream.

Explanation:

The ppm is the amount of solute (in milligrams) present in kilogram of a solvent. It is also known as parts-per million.

To calculate the ppm of oxygen in sea water, we use the equation:

$\text{ppm}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6$

Both the masses are in grams.

We are given:

The ppm concentration of nitrates = 3.0 ppm

Mass of nitrates = x

Mass of steam= m

Volume of steam = V = 2.5 L = 2500 ml ( 1 L = 1000 mL)

Density of steam = d = 1.0 g/mL

$M=d\times V=1.0 g/mL\times 2500 mL = 2500 g$

Putting values in above equation, we get:

$3.0=\frac{x}{2500 g}\times 10^6$

$x=0.0075 g$

Mass of nitrate = 0.0075 g

Moles of nitrate = $\frac{0.0075 g}{62 g/mol}=0.0001210 mol$

1 mole of nitrate ion is present in 1 mole of sodium nitrate.

Then 0.0001210 moles of nitrate will be present in :

$\frac{1}{1}\times 0.0001210 mol=0.0001210 mol$ of sodium nitrate;

Mass of 0.0001210 moles of sodium nitrate :

0.0001210 mol × 85 g/mol = 0.01028 g

0.01028 grams of sodium nitrate would there be in 2.5 L of the stream.

What are mineral acids?

Phantasy [73]

Answer:

mineral acids are obtained from one or more inorganic compounds which is a compound that lacks carbon and hydrogen bonds. Inorganic compound examples include water and carbon dioxide. Something all mineral acids do is form hydrogen ions and the joined together bases when it is dissolved in water.
