A wastewater sample contains two nitrogen species, namely ammonia and ...
Calculating the total nitrogen concentration in the wastewater:
To calculate the total nitrogen concentration in the wastewater, we need to convert the concentrations of ammonia and nitrate from milligrams per liter (mg/L) to milligrams nitrogen per liter (mg N/L).
Concentration of ammonia:
Given concentration of ammonia (NH3) = 34 mg/L
To convert the concentration of ammonia to nitrogen, we need to consider the atomic weight of nitrogen (N), which is 14 g/mol.
The molecular weight of ammonia (NH3) is 14 + (3 × 1) = 17 g/mol. This means that for every 17 g of ammonia, 14 g represents nitrogen.
To convert the concentration of ammonia (NH3) to nitrogen (N), we can use the following formula:
Concentration of nitrogen (N) = (Concentration of ammonia (NH3) × Atomic weight of nitrogen) / Molecular weight of ammonia
Concentration of nitrogen (N) = (34 mg/L × 14 g/mol) / 17 g/mol
Concentration of nitrogen (N) = 28 mg N/L
Concentration of nitrate:
Given concentration of nitrate (NO3-) = 6.2 mg/L
To convert the concentration of nitrate to nitrogen, we need to consider the atomic weight of nitrogen (N), which is 14 g/mol.
The molecular weight of nitrate (NO3-) is 14 + (3 × 16) = 62 g/mol. This means that for every 62 g of nitrate, 14 g represents nitrogen.
To convert the concentration of nitrate (NO3-) to nitrogen (N), we can use the following formula:
Concentration of nitrogen (N) = (Concentration of nitrate (NO3-) × Atomic weight of nitrogen) / Molecular weight of nitrate
Concentration of nitrogen (N) = (6.2 mg/L × 14 g/mol) / 62 g/mol
Concentration of nitrogen (N) = 1.4 mg N/L
Total nitrogen concentration:
To calculate the total nitrogen concentration, we need to sum up the concentrations of ammonia and nitrate.
Total nitrogen concentration = Concentration of ammonia + Concentration of nitrate
Total nitrogen concentration = 28 mg N/L + 1.4 mg N/L
Total nitrogen concentration = 29.4 mg N/L
Rounding off the answer to one decimal place, the total nitrogen concentration in the wastewater is 29.4 mg N/L, which falls within the given range of '29,30'.
To calculate the total nitrogen concentration in the wastewater, we need to convert the concentrations of ammonia and nitrate from milligrams per liter (mg/L) to milligrams nitrogen per liter (mg N/L).
Concentration of ammonia:
Given concentration of ammonia (NH3) = 34 mg/L
To convert the concentration of ammonia to nitrogen, we need to consider the atomic weight of nitrogen (N), which is 14 g/mol.
The molecular weight of ammonia (NH3) is 14 + (3 × 1) = 17 g/mol. This means that for every 17 g of ammonia, 14 g represents nitrogen.
To convert the concentration of ammonia (NH3) to nitrogen (N), we can use the following formula:
Concentration of nitrogen (N) = (Concentration of ammonia (NH3) × Atomic weight of nitrogen) / Molecular weight of ammonia
Concentration of nitrogen (N) = (34 mg/L × 14 g/mol) / 17 g/mol
Concentration of nitrogen (N) = 28 mg N/L
Concentration of nitrate:
Given concentration of nitrate (NO3-) = 6.2 mg/L
To convert the concentration of nitrate to nitrogen, we need to consider the atomic weight of nitrogen (N), which is 14 g/mol.
The molecular weight of nitrate (NO3-) is 14 + (3 × 16) = 62 g/mol. This means that for every 62 g of nitrate, 14 g represents nitrogen.
To convert the concentration of nitrate (NO3-) to nitrogen (N), we can use the following formula:
Concentration of nitrogen (N) = (Concentration of nitrate (NO3-) × Atomic weight of nitrogen) / Molecular weight of nitrate
Concentration of nitrogen (N) = (6.2 mg/L × 14 g/mol) / 62 g/mol
Concentration of nitrogen (N) = 1.4 mg N/L
Total nitrogen concentration:
To calculate the total nitrogen concentration, we need to sum up the concentrations of ammonia and nitrate.
Total nitrogen concentration = Concentration of ammonia + Concentration of nitrate
Total nitrogen concentration = 28 mg N/L + 1.4 mg N/L
Total nitrogen concentration = 29.4 mg N/L
Rounding off the answer to one decimal place, the total nitrogen concentration in the wastewater is 29.4 mg N/L, which falls within the given range of '29,30'.
