Determine the mass of CO2 contained in the room V 100 m3, assuming that the volume fraction

Determine the mass of CO2 contained in the room V 100 m3, assuming that the volume fraction of CO2 in the air is 0.03, and the mass of 1 liter of CO2 is 1.96 g

Given:
V (air) = 100 m3
φ (CO2) = 0.03%
1 l CO2 = 1.96 g CO2

Find:
m (CO2) -?

1) Calculate the volume of carbon dioxide contained in the presented volume of air in the room:
V (CO2) = φ (CO2) * V (air) / 100% = 0.03% * 100/100% = 0.03 l;
2) Calculate the mass of carbon dioxide that corresponds to the resulting volume in the room. Make a proportion and solve:
1 liter CO2 – 1.96 g CO2;
0.03 l – xg CO2;
x = 0.03 * 1.96 / 1 = 0.0588 g.

Answer: The mass of carbon dioxide is 0.0588 g.
