ONE.
Zeros on either side of decimal point are not significant.
Number may be written as 4 x 10^(- 4)
and 4 is 1 significant figure.

1 (the only number significant is the 4). Zeros directly after the decimal don't count. Just think, you could write that same number as 4 x 10^-4 <---- which clearly only has one significant digit!

a good rule i always use
RULE: If you remove the zero from the measurement and it changes the value of the mesurement it is NOT significant
so if you remove the first 0 from .0004 it comes to .004 which means the measurement has been changed therefore it is not significant
how many significant digits does 204.203 have?
well the 2 and the 4 and the 2 and the 3 but what about the other two zeroes well let see if we remove them both do they change the value of the measurement, yes. therefore they are not significant and 204.203 has 4 significant digits

The zeros between the 4 and the decimal point are merely place holders and tell you nothing about the precision of the number and so do not count.

The correct answer is 1. Only the 4 is significant
I suppose someone could construct a rule of some kind to handle this question.

Leading zeros are not significant so the answer is indeed 1.

Probably one...it depends on whether the implied, trailing zeros after the four are actually measured. If they are measured, they should be reported, and the number of sig figs would increase.

One, because the leading zeros do not count.
(if it was 0.00401, then it would be three, because the last zero is not leading)
