Between 1857 and 1992, carbon dioxide (CO2) concentration in the atmosphere rose from roughly 290 parts per million to 380 parts per million. Assume that this growth can be modeled with an exponential function Q=Q0×(1+r)t. Complete parts (a) and (b) below.
a. By experimenting with various values of the growth rate r, find an exponential function that fits the data for 1857 and 1992.
r=
b. Use this exponential model to predict when the CO2 concentration will double its 1857 level.
According to this model, the CO2 concentration will double its 1857 level in ____

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...

9. The concentration of carbon dioxide in the atmosphere has been increasing since the industrial revolution. In 2001, the concentration was 369 ppm (parts per million) and today (in 2019) it is 413 ppm. Assuming that the mass of the atmosphere is 5.2 x 1018 kg and has an effective molar mass of 29.0 g/mol (~80% N2, 20% O2), how many kg of CO2 have been added to the atmosphere since 2001? Note: 1 ppm = 1 umol per mole...
