For 1.00 L sample: (divide %vol by 100)
Ideal gas law:
T = 25°C + 273.15 = 298.15 K
Solving for moles of each gas:
A sample of air contains 78.08% nitrogen, 20.94% oxygen, 0.05% carbon dioxide, and 0.93% argon, by volume. How many molecules of each gas are present in 1.00 L of the sample at 25°C and 1.00 atm?
