How many single shots can you make from a 5lb Espresso Bag?

a bunch!! It takes 7 grams per out to about 324 shots...but then again there is some grinder...probably between 300-312...
Even though we all have standard misurament in ours coffee training,
one day I decide to try myself with a scale,
7 grams of coffee doesn't make a good single shot, my perfect single shot takes 11 grams
