There is a very nice explanation written here:
http://astronomy.swin.edu.au/~gmackie/billions.html
The current estimate is 130 billion galaxies each with 400 billion stars on average. That's 50,000 billion billion stars. (5x10^23 in scientific notation).
Compare that number to the 5000 that we can see with the naked eye in dark areas!
The number I gave above for the number of stars is also equal to the number of molecules in half an ounce (15 gram) of water.

There are many stars in the universe as there are galaxies to contain them and gas in the universe to create them.

The jury's still out on this one. There are probably about 400 billion in the Milky Way alone, and even that may be larger.

As Koala Lumber said - sand on the beach. This article from the ESA gives a bit more detail:
