How many milligrams of CO exist in 12000 liters of air with 10 ppm of CO?
VARVARA [1.3K]

Answer:

The mass of CO in 12,000 Liters of air is 12\times 10^4 mg.

Explanation:

The ppm is the amount of solute (in milligrams) present in one Liter 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}(mg)}{\text{Volume of solution}(L)}

The ppm concentration of CO = 10 ppm

Mass of CO = m

Volume of air = 12,000 L

10 =\frac{m}{12,000 L}

m=10\times 12,000 mg=120,000 mg=12\times 10^4 mg

The mass of CO in 12,000 Liters of air is 12\times 10^4 mg.
