To determine how much air must be processed to yield 20 tons of CO2, we can use the percentage concentration of CO2 in the atmosphere.
Given that the atmospheric CO2 concentration is 0.033%, we can convert this percentage to a fraction:
\[ 0.033\% = \frac{0.033}{100} = 0.00033 \]
This means that in every 1 ton of air, there are 0.00033 tons of CO2.
To find out how much air is needed to yield 20 tons of CO2, we can set up the equation:
\[ \text{Air (in tons)} = \frac{\text{CO2 (in tons)}}{\text{CO2 concentration (fraction)}} \]
Substituting the values we have:
\[ \text{Air} = \frac{20 \text{ tons}}{0.00033} \]
Calculating this gives:
\[ \text{Air} \approx 60606.06 \text{ tons} \]
This approximates to about 60,000 tons of air.
So, the best answer from the options would be:
**b) 60 000**
