Cellular respiration is the process that take place in the mitochondrion of a cell, it involves use of glucose from photosynthesis to produce energy in form of ATP and formation of CO2 and water. In this case, the Carbon dioxide formed passively diffuses out of the cell and Oxygen is pumped in and forces CO2 out. In this process oxygen acts as a electron acceptor.

in the reaction c o2 → co2, 18 g of carbon react with oxygen to produce 72 g of carbon dioxide. what mass of oxygen would be nee
Strike441 [17]
From the given balanced chemical reaction,
                                   C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
           18 g x (32 g oxygen / 12 g carbon) = 48 grams. 
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
                      72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams
