Question

Glucose, C₆H₁₂O₆, Calculate the number of grams of oxygen required to convert 33.0 g of glucose to CO₂ and H₂O.

a. 48.0 g

b. 96.0 g

c. 144.0 g

d. 192.0 g

Answer 1

The number of grams of oxygen required to convert 33.0 g of glucose to CO₂ and H₂O is 192.0 g.

Step-by-step explanation:

To calculate the number of grams of oxygen required to convert 33.0 g of glucose to CO₂ and H₂O, we need to use the chemical equation and mole ratios. Firstly, we balance the equation: 6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂. From this equation, we can see that 6 moles of glucose react with 6 moles of oxygen to produce 6 moles each of CO₂ and H₂O. The molar mass of oxygen is 32 g/mol, so 6 moles of oxygen would be 192 grams, which is the answer choice (d) 192.0 g.
