method to measure soluble organic carbon in seawater includes oxidation of the organic materials to CO2 with K2S2O8, followed by
dusya [7]

Answer:

The ppm carbon in the seawater is 104.01.

Explanation:

Mass of seawater = 6.234 g

Mass of carbon dioxide gas  produced = 2.378 mg = 0.002378 g

1 mg = 0.001 g

Moles of carbon dioxide gas = \frac{0.002378 g}{44.009 g/mol}=5.4034\times 10^{-5} mol

1 mol of carbon dioxde gas has 1 mole pf carbon atoms,then 5.4034\times 10^{-5} mol will have ;

1\times 5.4034\times 10^{-5} mol=5.4034\times 10^{-5} mol of carbon

Mass of 5.4034\times 10^{-5} mol of carbon ;

12 g/mol\times 5.4034\times 10^{-5} mol=0.0006484 g

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)

=\frac{0.0006484 g}{ 6.234 g}\times 10^6=104.01 ppm

The ppm carbon in the seawater is 104.01.
