3 Mg + 1 Fe2O3 →2 Fe + 3MgO
Type of Reaction: Single displacement.
You’ll need to set up a convention from moles over atoms to atoms over moles
There are 0.0214 mol Cs in 1.29×10²² atoms Cs.
Use <em>Avogadro’s number</em> to convert atoms of Cs to moles of Cs.
Moles of Cs = 1.29×10²² atoms Cs × (1 mol Cs /6.022 × 10²³ atoms Cs) = 0.0214 mol Cs
Answer: Formula weight is the sum of weights of all the atoms in an empirical formula of a molecule. Molecular weight is the collection of weights of all the atoms in a molecular formula.
