9 zeros
As a number it is: 90,000,000,000 which has 10 zeros in it
A billion (or 6 billion) has 9 zeros.
If you meant a number followed by 100 zeros, that would be Google if the number was a 1. If you meant 100 zeros followed by a number, that would be just that number.
11 zeroes.

100 000 000 000 is a hundred billion
100 nonillion or 100 thousand billion billion billion
A googol is one followed by 100 zeros ( 100 digits). That is less than a billion digits, for sure. But a googolplex is one follwed by a googol number of zeros. That is more than a billion digits, for sure.
a billion has nine zeros.
It is a very large number which would be expressed in scientific notation
9 zeros
It has 21 zeros, because 'Giga' means 'a Billion'. Thus, one GigaTrillion is 1 Billion-Trillion. A billion has 9 zeros, and a trillion has 12 zeros. However, if you are referring to the United Kingdom, a billion has 12 zeros and a trillion has 18 zeros, so it would be 30 zeros.
any number containing 100 zeros has 100 zeros but i'm assuming you mean a 1 fallowed by 100 consecutive zeros; that is a Googol or 10,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000,­000
