1000 has one significant digit (you don't know anything for sure about the hundreds, tens, or units places; the zeroes may just be placeholders; they may have rounded something off to get this value) 1000.0 has five significant digits (the ".0" tells us something interesting about the presumed accuracy of the measurement being made: that the measurement is accurate to the tenths place, but ...

Chemistry 12 - Review of Significant Digits. The rules for zeros in significant digits are as follows: a) All zeros between non-zero digits are significant. b) Zeros at the beginning of a number ( eg. 0.0095) are NOT SIGNIFICANT ! If the number 0.0095 was written in scientific notation, it would be: 9.5 x 10-3. The exponent is not counted as significant so this number has 2 significant digits ...

Clearly the third digit, which has been estimated by everyone, is an uncertain figure. The digits that are considered certain and the first estimated digit are called significant figures. The number of significant figures in a measurement depends upon the precision of the instrument. By applying the rules of significant figures, the calculated quantities will carry the same accuracy as the ...

A line above a zero or below it indicates that the zero is significant and it is the first estimated digit or the last significant digit. "Trailing" zeros (for decimals) which are to the right of the decimal point and to the right of any nonzero digit are significant because they indicate the measurement has been carried to that degree of precision. When adding or subtracting measurements you ...

There are two different rules for how many significant digits to keep in your answer when you do a calculation, depending on whether you are doing addition/subtraction or multiplication/division. Adding and Subtracting: Look for the number whose final significant digit ends in the farthest decimal place to the left, and then round your answer to that same decimal place. For example, how many ...

Rules for rounding. When making calculations with measured values, the answer will need to be rounded to the correct number of significant figures according to the following rules. Round down whenever the digit following the last significant figure is a 0,1,2,3, or 4. For example, 30.24 becomes 30.2.
