Week 32 – Moles of Oxygen

To determine how many moles of oxygen are in each substance:

  • 0.55 mol of C6H12O6 x 6 moles of oxygen / mole of C6H12O6 = 3.3 moles of oxygen in 100 g of C6H12O6
  • 2.27 mol of CO2 x 2 moles of oxygen / mole of CO2 = 4.54 moles of oxygen in 100 g of CO2
  • Therefore, CO2 has more carbon atoms than C6H12O6 in 100 g of each sample
