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:
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
Putting values in above equation, we get:
Mass of nitrate = 0.0075 g
Moles of nitrate =
1 mole of nitrate ion is present in 1 mole of sodium nitrate.
Then 0.0001210 moles of nitrate will be present in :
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.
