Question

All cells in living organisms undergo cellular respiration. The chemical reaction for cellular respiration is stated below. (Glucose Oxygen → Carbon Dioxide Water) If glucose and oxygen, with a total mass of 65.7 grams are reacted, what total mass of carbon dioxide and water will be produced?

Answer 1

Answer : The total mass of carbon dioxide and water produced will be, 65.7 grams.

Explanation :

Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

This also means that total mass on the reactant side must be equal to the total mass on the product side.

The balanced chemical reaction will be,

`C_6H_(12)O_6+6O_2\rightarrow 6CO_2+6H_2O`

According to the law of conservation of mass,

Total mass of reactant side = Total mass of product side

Total mass of
`C_6H_(12)O_6+6O_2` = Total mass of
`6CO_2+6H_2O`

As we are given :

Total mass of
`C_6H_(12)O_6+6O_2` = 65.7 grams

So,

65.7 grams = Total mass of
`6CO_2+6H_2O`

Therefore, the total mass of carbon dioxide and water produced will be, 65.7 grams.
