If a gram of antimatter meets a kilogram of matter the amount of mass to survive is?

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.

How many grams of antimatter are needed to react with 5 g of matter?
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.
At what temperature does antimatter form?
It isn't a matter of temperature. It is created in high-speed collisions like those observed in the hadron particle collider. Antimatter is naturally occurring. It has only been created in minute amounts and costs a fortune. One kilogram of antimatter would create an explosion with the power of a 20 megaton nuclear bomb.
Where to find antimatter?
Anywhere with elementary particles having the mass and electric charge of ordinary matter. Which basically all antimatter is.
What is the role of gravitational force between matter and antimatter?
Sir Issac Newton proposed theory of gravity. He formulated the relation between the force of gravity and the mass and the distance between the masses. This theory failed to explain as to why there is attraction between the masses and not repulsion. With every attraction you have to have corresponding repulsion. That problem is resolved with the discovery of antimatter. So like attracts like. So matter attracts matter and antimatter attracts antimatter. This fallows that matter repel antimatter. So force of gravity between the two masses of matter or two masses of antimatter is directly proportional to the product of masses or anti-masses (Antimatter). The force of repulsion will be directly proportional to the product of mass and anti-mass (Antimatter). It fallows that the force of repulsion is inversely proportional to square of distance between the two.
Is all life composed of matter?
Yes unless its antimatter.
If 1gram body of antimatter meets a 10gram body of matter which survives?
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.
What are two questions physicists have regarding antimatter?
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?
What is the meaning of annhilated in The only way for ALL this energy to be released is for the kilogram of water to be totally annhilated?
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.
Why is there far more matter than antimatter in the visible universe?
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.

How come the universe is made of matter and not antimatter?
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".
Why matter overcome antimatter?
That is one of the unsolved problems in cosmology. There seems to be a slight difference between matter and antimatter, that is, the symmetry between matter and antimatter is not perfect. But the details of baryogenesis are not known yet.
How could it B true that matter and antimatter at start of big bang With little amount of matter left in end winning B enough 2 make up all we see today?
In the early universe, matter and antimatter were created in equal amounts. As the universe cooled and expanded, there was a slight imbalance in favor of matter over antimatter. This allowed the matter to survive and form the structures we see today, while most of the antimatter annihilated with matter, resulting in the predominance of matter in the universe.
Are antimatter weapons possible?
Yes, but anti-matter is extremely expensive to make for the amount of energy that can be produced from it. Therefore anti-matter weapons are not feasible.
Anything that has volume or mass?
Matter, or antimatter.
Why the antimatter disappear in universe?
When antimatter comes into contact with matter, they annihilate each other.
Why was matter in greater amount during formation of the Universe?
Because (we think) both matter and antimatter was formed initially, most of which was canceled out to form more energy.
