Question 6 of 1010 PointsAnimals breathe oxygen and release carbon dioxide during cellular respiration according to the equation below. How much oxygen is needed to produce 120 grams' ofcarbon dioxide?C₂H12O6 + 602 6CO₂ + 6H₂O

Sagot :

In this question, we have the following reaction, which is the cellular respiration reaction:

C6H12O6 + 6 O2 --> 6 CO2 + 6 H2O

We have:

120 grams of CO2 being produced

The molar ratio between CO2 and O2 is 6:6, which means the same amount of moles produced of CO2 will be the same amount used of O2

Now we find the number of moles of CO2, using its molar mass = 44.01g/mol

44.01 grams = 1 mol

120 grams = x moles

44.01x = 120

x = 120/44.01

x = 2.73 moles of CO2

If we have 2.73 moles of CO2, we will also have 2.73 moles of O2, and to find its mass, we will also use the molar mass of O2 = 32g/mol

32 grams = 1 mol

x grams = 2.73 moles

x = 2.73 * 32

x = 87.4 grams of O2

The amount required of oxygen gas to produce 120 grams of CO2 based on the cellular respiration reaction will be 87.4 grams
