I'm trying to figure out about how many grams of water each gram of ground coffee will retain after brewing is complete. I've done a little reading and a little math (I know... dangerous combination) and came up with something around 40-45 grams water per 20 grams ground coffee. Sound about right?

It's easy to figure out. Just weigh your water going in, then the beverage weight in the cup. The difference is the liquid retained, then divide by grams of ground coffee to get the per gram ratio. I've found it to vary a bit by coffee, but usually between 1.5 and 1.75.
