In 2013, CO 2 levels surpassed 400 ppm for the first time in recorded history. This recent relentless rise in CO 2 shows a remarkably constant relationship with fossil-fuel burning, and can be well accounted for based on the simple premise that about 60 percent of fossil-fuel emissions stay in the air.

Convert from ppm to g/m^3 as explained above, then realize that 1 m^3 = 1000 liters, so the gas phase part of your tank is 1/5 of a cubic meter.
