How many significant figures does 0.00120 have?
3 significant digits
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.
