The average adult exhales about 1.0 kg of carbon dioxide each day. how much oxygen is needed in metabolizing glucose (c6h12o6, 180 g/mol) to make that much carbon dioxide? somebody answer this for me i searched for it and it brought me to this site but when i try to get the answer it just brings me to this page. but no answer to be found

0.72727 kg of oxygen is needed in metabolizing glucose to make 1.0 kg of carbon dioxide.

Explanation:

Mass of carbon dioxide exhaled by an adult = 1.0 kg = 1000 g

Moles of carbon dioxide =

According to reaction,6 moles of carbon dioxide is produced when 1 mole of glucose.

Then 22.7272 moles of carbon dioxide will be produce by:

of glucose

According to reaction 1 mol of glucose reacts with 6 moles of oxygen :

Then 3.7878 moles of glucose will react with

of oxygen

Mass of 22.7272 moles of oxygen  gas:

0.72727 kg of oxygen is needed in metabolizing glucose to make 1.0 kg of carbon dioxide.

the answer is option a.
