Density varies - in cold, denser areas there may be as many as 10^12 molecules per cubic meter; in hotter less dense areas, about only 100 ions in the same volume. One source puts the average at one million atoms per cubic meter. Compare to about 10^25 molecules per cubic meter for air.

Interstellar chunks of matter forming a belt between mars and Jupiter are what?
Asteroid belt. They are not "interstellar", of course.
What is interstellar matter made of?
The interstellar medium is an extremely sparse (tenuous) mix of gas and dust, some of the gas being ionized, some atomic, and some molecular. By composition the gas is largely hydrogen, with smaller amounts of helium and very small amounts of heavier elements. There are also cosmic rays which are protons and nuclei which have been accelerated to near-relativistic speeds. In cooler, high-density areas, the interstellar medium can become as dense as one ten-billionth that of air.

What does intersellar matter provide material for?
Interstellar matter floats around, and if enough of it coalesces, then it can turn into a new star or cluster of stars.
Another name for the interstellar matter that will eventually form a star is?
