Question

air contains about 0.03% of carbon dioxide calculate its concentration parts per million​

Answer 1

The concentration of carbon dioxide in air is 300 ppm

Explanation:

We are given:

0.03 % of carbon dioxide in air

This means that 0.03 grams of carbon dioxide is present in 100 grams of air

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:

Mass of carbon dioxide = 0.03 g

Mass of air = 100 g

Putting values in above equation, we get:

$\text{ppm of carbon dioxide in air}=\frac{0.03}{100}\times 10^6\\\\\text{ppm of carbon dioxide}=300$
