WebA related measure of concentration is the mass concentration ρX, representing the mass of X per unit volume of air (we will also use ρX to denote the mass density of a body, i.e., its mass per unit volume; the proper definition should be clear from the context). ρX and nX are related by the molecular weight MX (kg mol-1)ofthe gas: (1.8) WebThe large growth in global CO 2 emissions has had a significant impact on the concentrations of CO 2 in Earth’s atmosphere. If we look at atmospheric concentrations over the past 2000 years, we see that levels were fairly stable at 270 to 285 parts per million (ppm) until the 18 th century. Since the Industrial Revolution, global CO 2 …
