<h3>Answer: 0.0000000651</h3>

There are seven "0"s between the decimal point and the digit "6".

======================================================

Explanation:

The number $6.51 \times 10^{-8}$ is in scientific notation.

The exponent -8 tells us to move the decimal point exactly 8 spots to the left to get the answer 0.0000000651

In other words, we'll move the decimal point one spot to the left to go from 6.51 to 0.651

Then we move it another seven spots to the left to arrive at 0.0000000651

This is why there are seven "0"s between the decimal point and the digit "6".
