You haven't posted enough information about your growing methods/conditions. It is, therefore, impossible to predict how much your plant will yield. It will range between 1 gram of dry bud to 4 ounces of dry bud (maybe even more, but 4 is pushing it..).
If this is your first grow, concentrate on not killing the plant. You'll over or under feed it, if you train it you'll snap a branch or two, ..., things will go wrong. Any yield should be regarded as a win for your first grow. If you get all the conditions right, and you manage your grow meticulously, you should yield around a dry ounce.
