If the big bang took place at an exact time and an exact place and ever since the universe has been expanding at a finite rate; does this give creedance to the idea that there is a finite amount of matter which occupies a finite amount of space? I realize that there are practical difficulties with providing an actual value, I am interested if the concept is theoretically valid. Or in other words my question is: "At a given moment in time can the total amount of matter in existance be quantified?" Thanks.

There are a lot of 'if's in your premise. Yes, it is reasonable to consider the total mass in the universe to be quantified and constant, and to occupy a finite amount of space. Some are expressing the idea that there is no such thing as 'space' outside the boundaries of the matter in the universe.
At one time, some contemplated the idea of continuous creation of matter. I don't think anyone is still considering this idea.
