How many significant figures does 0.00120 have?
We are given a number 0.00120, we have to find its significant figures. Since it has zero before the decimals, they will be insignificant, and after the decimal all are significant, so,
3 significant figures
. Hence, 0.00120 have 3 significant digits.
How many significant figures are in the measurement 1300 g?
Example: 130.00 g (
5 sig
figs). The number 1,300 has trailing zeros
How many significant digits does 100 have?
100 has
1 significant figure
. 4) Zeros in the beginning of a number whose only function is to place the decimal point are not significant. Example: 0.0025 has 2 significant figures.

in the number 20.
How many significant figures does 1500.00 have?
Thus, in 1,500 m, the two trailing zeros are not significant because the number is written without a decimal point; the number has two significant figures. However, in 1,500.00 m, all
six digits are significant
because the number has a decimal point.
How many significant figures does 2.02 have?
This number has
three significant figures
. Trailing zeros, which are zeros at the end of a number, are significant only if the number has a decimal point.
