Stoichiometry is converting one unit to another unit to solve a problem. Oftentimes we learn stoichiometry in chemistry class and think, "When will I ever use this?" The answer: the grocery store.Suppose you want to buy three pounds of the cheapest cheddar cheese at the store. One cheese block costs $4.50 for 12 oz. and the other costs $12.00 for one pound. Which is cheaper? How much are you going to pay?The easy way would be to buy three pounds of the $12.00 cheese. You would pay $36 for three pounds and get ripped off.With a little stoichiometry you can find how many little blocks you would need: 3lbs*(16oz/lb)*(1block/12oz) = 4 blocks.4 blocks * ($4.50/block) = $18You would pay half the price for the same amount of cheese by buying the littler blocks.The same stoichiometry process applies to buying any kind of meat, cereal, or produce at the store to get the best price.
