🤓 Based on our data, we think this question is relevant for Professor Guo's class at LAMAR.

Solution: The atmospheric concentration of CO2 gas is presently 390 ppm (parts per million, by volume; that is, 390 L of every 106 L of the atmosphere are CO2).What is the mole fraction of CO2 in the atmosphere?

Problem

The atmospheric concentration of CO2 gas is presently 390 ppm (parts per million, by volume; that is, 390 L of every 106 L of the atmosphere are CO2).

What is the mole fraction of CO2 in the atmosphere?

Solution

Avogadro's law states that the volume of a gas is directly proportional to the number of molecules of the gas.
