How many milligrams of CO exist in 12000 liters of air with 10 ppm of CO?
1.2 × 10^4
12 × 10^3
12 × 10^5
12 × 10^4

The mass of CO in 12,000 Liters of air is .

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:

The ppm concentration of CO = 10 ppm

Mass of CO = m

Volume of air = 12,000 L

The mass of CO in 12,000 Liters of air is .

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

i think its 100.

hope this !
