1 gram + 1000 grams = 1001 grams. If you prefer to exclude the gamma rays, one gram of matter will annihilate with 1 gram of antimatter, and 999 grams of "normal" matter will be left. The remaining 2 grams are in the gamma rays, of course.
During a matter-antimatter reaction, particles of matter and antimatter collide and annihilate each other, releasing a large amount of energy in the form of gamma rays and other particles.
Exactly 5 grams of antimatter will completely annihilate 5 grams of matter, producing an enormous shower of high energy gamma rays. In total a mass of 10 grams will be converted to the equivalent amount of energy.
When antimatter touches matter, they annihilate each other, releasing a large amount of energy in the form of gamma rays. This process is called annihilation.

If you were to touch antimatter, it would result in a violent and explosive reaction, releasing a large amount of energy. This is because when antimatter comes into contact with regular matter, they annihilate each other, converting their mass into energy.

It is not currently known why there is more matter than antimatter. Some assymetries (differences between matter and antimatter) have been found, but they are very slight, and it is not clear how this could have been enough to create the matter we see today.
Initially the 9g of remaining matter would survive. Each particle of antimatter can only annihilate with one other particle of antimatter. At this point the 1g of antimatter would cause an explosion equivalent to that of 200000 pounds of TNT. Causing both groups of matter and antimatter to be obliterated.
That means that it disappears as normal matter and is converted into "pure energy". Note that this is not possible for normal matter, unless it meets an equal amount of antimatter.

It may have to do with the way the universe was created. Certainly if there was a lot of antimatter created, much of it may well have come in contact with matter through the billions of years the universe has existed. That would have resulted in the conversion of that antimatter (along with a like amount of matter) into energy. There may not have been much antimatter around to begin with, too. But, since the amount of visible matter represents less matter than has been calculated to exist in the uinverse, it may be that there is a good bit of antimatter out there somewhere. Not likely, but possible.

1. Why is there more matter than antimatter in the Universe? Or: Why is there matter at all? (If there were the same amount of matter and antimatter, and it came into contact, it would quickly get destroyed. 2. If antimatter is so abundant, how come we've never come in contact with it or have been able to observe it?
Antimatter is a type of matter that has the opposite properties of normal matter. When a particle of matter meets its corresponding antiparticle, they annihilate each other, releasing a large amount of energy in the process. Antimatter is rare in the universe and is mostly created in high-energy environments like particle accelerators.
That is not currently known. There is a slight assymetry between matter and antimatter, but so far, it seems that this assymetry is not enough to explain why there is only matter, and hardly any antimatter, in the Universe. Without such an assymetry, there wouldn't be either matter or antimatter in the Universe - just radiation. For more information about what is known, and what isn't, check the Wikipedia article on "Baryon asymmetry".
Antimatter is a type of matter with an unusual quality - it has properties that are opposite to those of normal matter. For example, when antimatter comes into contact with normal matter, they annihilate each other, releasing a large amount of energy. Antimatter is rare in the universe and is usually produced in high-energy processes like particle accelerators.
