## Homework Statement

Suppose ##10^{14} kg## of carbon dioxide was released into the atmosphere and absorbed completely, what is the percentage change of carbon dioxide concentration? Take initial atmospheric mass mixing ratio to be ## 5.7 \times 10^{-4} kg/kg##.

## Homework Equations

## The Attempt at a Solution

Using density of air as around ##29 g/mol##, the weight of the atmosphere is about ##10^{18} kg##. The percentage change is ##\frac{10^{14}}{10^{18}} \times 100 = 0.01%##? Where does the mixing ratio come in?
