1. Find the molar mass of C2H6O2:
* Carbon (C): 12.01 g/mol * 2 = 24.02 g/mol
* Hydrogen (H): 1.01 g/mol * 6 = 6.06 g/mol
* Oxygen (O): 16.00 g/mol * 2 = 32.00 g/mol
Total molar mass = 24.02 g/mol + 6.06 g/mol + 32.00 g/mol = 62.08 g/mol
2. Convert kilograms to grams:
* 1 kg = 1000 g
3. Calculate the number of moles:
* Moles = (mass in grams) / (molar mass)
* Moles = 1000 g / 62.08 g/mol
* Moles ≈ 16.11 moles
Therefore, there are approximately 16.11 moles in 1 kg of C2H6O2.
