What volume of oxygen at NTP is required to oxydize 100gram of glucose ?

1 answer

C6H12O6 + 6O2 ==> 6CO2 + 6H2O

mols C6H12O6 = grams/molar mass = ?

Convert mols glucose to mols O2 using the coefficients in the balanced equation. It takes 6 mols O2 for every mol glucose.

Now convert mols O2 to volume. Use PV = nRT at NTP. NTP is 20 C (293.15 K) and 1 atm.

Post your work if you get stuck.
