Moles Chemistry

Question

"In our bodies, sugar is broken down with oxygen to produce water and carbon dioxide."According to the following reaction, how many moles of carbon dioxide will be formed upon the complete reaction of 0.260 moles glucose (C₆H₁₂O₆) with excess oxygen gas?

glucose (C₆H₁₂O₆) (s) + oxygen (g) carbon dioxide (g) + water (l)

Answer 1

First, you must balance the equation:

C₆H₁₂O₆ + 6O₂ ==> 6CO₂ + 6H₂O

From this balanced equation you see that 1 mole glucose produces 6 moles of CO_2. Thus, 0.260 mol glucose x 6 mol CO₂/mol glucose = 1.56 moles
