S The metric system is called a decimal system because measurements of each type are related by factors of 10. 60 - neutrons (107-47) Because leading zeros do not count as sig figs, but zeroes sandwiched between non-zero figures do count. In the number 0.0025, the leading zeros (those to the left of the non-zero numbers) are not significant. The final answer is written so that it has the same number of decimal places as the measurement with the fewest decimal places. Two or more substances combine physically to make a mixture. 0.0070080 Five significant digits.
