Method to measure soluble organic carbon in seawater includes oxidation of the organic materials to CO2 with K2S2O8, followed by gravimetric determination of the CO2 trapped by a column of Ascarite. A water sample weighing 6.234 g produced 2.378 mg of CO2 (FM 44.009). Calculate the ppm carbon in the seawater.

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 =

1 mol of carbon dioxde gas has 1 mole pf carbon atoms,then will have ;

of carbon

Mass of of carbon ;

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

(Both the masses are in grams)

The ppm carbon in the seawater is 104.01.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

its first and third is your answer i did the qustion the fourth isnt right
