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

Nataly_w [17]

Answer: 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:

$\text{ppm}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 10^6$

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:

$2=\frac{\text{Mass of iron}}{280g}\times 10^6\\\\\text{Mass of iron}=\frac{2\times 280}{10^6}=0.00056g=0.56mg$

Conversion factor used: 1 g = 1000 mg

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