Calculate the moles of oxygen produced by reacting the carbon dioxide exhaled by a human in a day.

Answer 1

To calculate the moles of oxygen produced by reacting the carbon dioxide exhaled by a human in a day, we need to remember that the reaction is:

6 CO2 + 6 H2O -> C6H12O6 + 6 O2

From this reaction, we can see that for every 6 moles of carbon dioxide produced, 6 moles of oxygen are produced.

The average human exhales about 2.3 pounds (1.04 kg) of carbon dioxide per day. The molar mass of carbon dioxide (CO2) is about 44.01 g/mol.

First, we need to convert the mass of carbon dioxide exhaled by the human into moles:

1.04 kg * (1000 g / 1 kg) * (1 mol / 44.01 g) = 23.6 mol CO2

Since the reaction shows that for every 6 moles of CO2, 6 moles of O2 are produced, the number of moles of oxygen produced will be equal to the number of moles of carbon dioxide.

Therefore, the amount of moles of oxygen produced by reacting the carbon dioxide exhaled by a human in a day is 23.6 moles.
