Often a zero that is difficult to tell if it is significant or not can be clarified by using scientificnotation.Exercise 3: Determining significant figures:On the line, write the number of significant figures in each measurement:d) 2.40 cma) 252 me) 0.004 5 sb) 2503 cmc) 0.01 kgf) 3.060 x 10 m³The number of significant figures in a measurement is also sometimes called the accuracyof the measurement (but it has nothing to do with how well you performed in making themeasurement!). When using the rules of significant figures in calculations, it will depend onthe calculation:When multiplying or dividing two or more quantities, the number of significantfigures in the final result is the same as the number of significant figures in the leastaccurate of the factors being combined.This will be the rule you will need to follow most often in lab. However, you may also haveto add or subtract measurements. Another rule then applies, one that looks at theprecision of the measurement.The precision is the smallest unit in which the measurement was made, the decimalposition of the last significant figure. The rule is:When adding or subtracting measurements, be sure all the units are the same. Thenperform the operation and round the result to the same precision as the least preciseтeasurement.If you have a combination of operations, use same order of operations with the significantfigures as you do when performing the operation itself. Remember, using these rules willapproximate the uncertainty by giving a reasonable number of significant figures to use inthe answer. To find the true uncertainty, you would need to go through a series ofcalculations.Examples:
