Three - the first two zeros are placeholders.

8 significant figures. The decimal makes the first 5 zeros significant while the two zeros after the decimal are significant because there is a significant figure earlier (2).

all the zeros are significant. there are four significant figures.

There are five significant figures in 10001. The 1s are significant because they are non-zero digits. The zeros are significant because they are "captured" zeros, meaning they are between non-zero digits.

3 significant digits because first zeros are just placeholders

Five. Zeros in between significant digits are significant and trailing zeros that are after the decimal are significant.

three, leading zeros are not significant and trailing zeros are significant if there is a decimal. trailing zeros are not significant if there is no decimal zeros in the middle of numbers are significant

None of the zeros in that number are significant.

All the digits are significant in this case. A zero between other digits is always significant, and all zeros after the decimal point are significant.

One of the rules of significant figures is that leading zeros are not significant; therefore, 0.00034 will only have TWO significant figures (3 and 4).

Four of the zeros are significant... the two zeros after the digit 5 0 are simply 'place fillers'.

Just 1. The zeros before the 5 are just placeholders, not significant figures. However, if the number were 0.0500, then there would be 3 sig figs. This is because the extra zeros represent greater accuracy in the measurement.

Five - any zeros after the decimal are significant unless they're placeholders. Any zeros between significant digits are significant.
