176 grams of carbon dioxide will be produced.
Step-by-step explanation:
To find the amount of carbon dioxide produced, we first need to know the molecular weights of both oxygen and carbon dioxide.
Molecular weight of oxygen = 32.
Molecular weight of carbon dioxide = 44.
So number of moles of oxygen present in 128 grams of oxygen = 4.
Reaction between carbon dioxide and oxygen is C + O2 =CO2.
So 1 mole of oxygen produces 1 mole of carbon dioxide.
So 4 moles of carbon dioxide will be produced.
So, weight of carbon dioxide produced = 176 grams.
