For this problem, we’re being asked to determine the number of oxygen atoms in a 9.00 g sample of vanadium (V) oxide (V2O5). . The flow for this problem will be like this:
Mass of V2O5(molar mass of V2O5) → Moles of V2O5 (mole-to-mole comparison) → Moles of O (Avogadro’s number) → Atoms of O
Calculate the number of oxygen atoms in a 9.00 g sample of vanadium (V) oxide (V2O5).
Be sure your answer has a unit symbol if necessary, and round it to 3 significant figures.
