Glycogen stored in the liver lasts for 12-14 hours, how much in weight is this glycogen?

So I'm a undergrad majoring in biology, and while taking my Macro-molecules and Metabolism class my professor remarks that glycogen stored in the liver can last for 12-14 hours, to which I asked how much glycogen is that? He didn't have an answer, so I'm asking it here.

Typically about 100 grams. This can also last to fuel the body for up to 22 hours before the body switches to breaking down protein and fat for energy. Muscles store about 400 grams of glycogen, but those bastards are selfish and since they lack the enzyme glucose-6-phosphatase, they cannot convert G6P to glucose to be used to regulate blood glucose.
