ANY TIME you are going from an amount of one substance to an amount of another substance, you MUST use a mole to mole ratio.

ANY TIME you are going from an amount of one thing to an amount of another thing, work in 3 steps: Step 1: convert the given information to moles Step 2: use a mole-to-mole ratio Step 3: convert the moles to whatever is asked for
