Co2 concentrations in the atmosphere are stable around 408 ppm (parts per million), which translates to approximately 1016 molecules cm-3 . what is the mass concentration of co2 in units of μg m-3 ? given the annual rate of increase of co2 of 1.6 ppm yr-1 , what is the projected co2 concentration in 2100 in units of ‘ppm’ and ‘μg m-3 ’? hint: assume an air density of 2.4×1019 molecules cm-3 .

Select the correct answer. when carbon dioxide dissolves in water, it sometimes reacts with water to form carbonic acid as in this balanced equation: co2 + h2o → h2co3. if 495 milliliters of carbon dioxide at 25°c and 101.3 kilopascals reacts with excess water, what is the theoretical yield of carbonic acid? use the periodic table and the ideal gas resource a. 0.889 g b. 1.10g c. 1.27g d. 2.02g what's the answer! quick!
