Mass of CO2 = 12+(16*2) = 44 g/mol
Mass of carbon = 12 g/ mol
Percent mass of carbon in carbon dioxide = 12/44*100% = 27.27%
What is the percent by mass of carbon in carbon dioxide (CO2)? What is the percent...
Concentration of CO2 in the Atmosphere Levels of carbon dioxide (CO2) in the atmosphere are rising rapidly, far above any levels ever before recorded. Levels were around 278 parts per million in 1800, before the Industrial Age, and had never, in the hundreds of thousands of years before that, gone above 300 ppm. Levels are now nearing 400 ppm. Table 1 shows the rapid rise of CO2 concentrations over the last 50 years, also available in CarbonDioxide.1 We can use...
