indicate this by writing the measurement as. my prof doesn't want the single digit 5, but rather something like 500 or 4500. In the number 0.0025, the leading zeros (those to the left of the non-zero numbers) are not significant. And that would be the estimated digit at 42.50 g all trailing zeros. The final digit in a precise measurement is obtained by estimating. Be able to read a ruler and give two estimated digits after that. If they put a decimal here then the zero would be the last significant figure. there five significant figures for 204.52 g. state the significant figures in each of the following measurements 625.000 mm, the significant number of 625.000 mm. 552.8 g 0.50 mL = ? So the estimated digit of the two if we have 40 500 miles as represented, the zeros are not significant just the four and the five R. So the estimated digit would be the five. Leading zeros before a number are not significant. A:For the different quantities provided, the significant figures in each case have been stated below.
