- The atmosphere is a highly complex gaseous mixture that sustains life on Earth. Approximately 99% of the air is composed of nitrogen (N2) and oxygen (O2). The remaining 1% is made up of a variety of other gases, including carbon monoxide (CO), hydrogen (H2), and ammonia (NH3), among many others. Because most of the gases that comprise the atmosphere are present at very low levels (<0.002%), their quantities are often expressed in parts per million (ppm) or parts per billion (ppb) rather than as a percent. Ozone (O3) is found in the troposphere at 2.5×10−6%. Convert this value to parts per million. [O3]= _______ ppm The atmosphere contains 2.9×10−7%2.9×10−7% nitrogen dioxide (NO2). Convert this value to parts per billion. [NO2]= _______ ppb Atmospheric methane (CH4) is present at 1983 ppb. Convert this value to a percentage.
