What mass of iron is found in 280 g of 2 ppm solution?

The mass of iron found in the solution is 0.56 mg

Explanation:

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:

Concentration of iron = 2 ppm

Mass of solution = 280 g

Putting values in above equation, we get:

Conversion factor used:  1 g = 1000 mg

Hence, the mass of iron found in the solution is 0.56 mg

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
