How many significant figures does 6.022 have?

Answer 1

The number 6.300 has four significant digits. We must assume that the only reason for including the two zeroes at the end is to express the precision of the measurement (whatever it was that was measured to yield this number). If you were only confident about the first two numbers, you would express it as 6.3 rather than 6.300 as you did.
