Answer to Question #181207 in Chemistry for Henry

Question

How many moles of oxygen can be burned biologically when 42.26 g of carbon dioxide is produced

Answer 1

C₆H₁₂O_6(s) + 6O_2(g) → 6CO_2(g) + 6H₂O_(l)

According to the equation, n (O₂) = n (CO₂).

n (CO₂) = m / M

M (CO₂) = 44.01 g/mol

n (O₂) = n (CO₂) = 42.26 / 44.01 = 0.96 mol
