Final answer:
In 247 g of Fe₂₃, there are approximately 1.547 moles of the compound, calculated using the molar mass of Fe₂₃ which is 159.70 g/mol.
Step-by-step explanation:
To calculate the number of moles of Fe₂₃ in 247 g of the compound, we use the formula:
moles = mass / molar mass
The molar mass of Fe₂₃ (iron(III) oxide) is 159.70 g/mol. Given this, we can set up our calculation:
moles of Fe₂₃ = 247 g Fe₂₃ / 159.70 g/mole Fe₂₃
This simplifies to approximately:
moles of Fe₂₃ = 1.547 mol Fe₂₃
Thus, 247 g of Fe₂₃ contains about 1.547 moles of the compound.
