1. Find the molar mass of glucose (C6H12O6):
* Carbon (C): 6 atoms * 12.01 g/mol = 72.06 g/mol
* Hydrogen (H): 12 atoms * 1.01 g/mol = 12.12 g/mol
* Oxygen (O): 6 atoms * 16.00 g/mol = 96.00 g/mol
* Total molar mass: 72.06 + 12.12 + 96.00 = 180.18 g/mol
2. Convert grams of glucose to moles:
* Moles = (mass in grams) / (molar mass)
* Moles = 720 g / 180.18 g/mol = 4 moles
3. Use Avogadro's number to find the number of molecules:
* Avogadro's number: 6.022 x 10^23 molecules/mol
* Number of molecules = (moles) * (Avogadro's number)
* Number of molecules = 4 moles * 6.022 x 10^23 molecules/mol = 2.409 x 10^24 molecules
Therefore, there are approximately 2.409 x 10^24 molecules in 720 grams of glucose.
