So you have a reaction. You have either been given information on another reactant, or a product.
If the reactant (ensure it is the limiting reactant if there are multiple) or a product, find the moles
Use the mole ratio to find the moles of oxygen
Than find mass of oxygen using mass = moles x Mr

Assume you have one mole of butane.

Using the equation, how many moles of oxygen would you therefore need to react completely with it?
