Significant Figures & Scientific NotationName: ______________________Date: _________ Block: _______Rules for Determining Significant Figures Involving ZerosRuleExamples ofMeasurementsNumber ofSignificantFigures1. All nonzero digits are significant 2. All zeros between two nonzero digits are significant3. Zeros to the right of a nonzero digit, but no decimal point are not significant. If such zeros are next to a decimal point, they are significant.4. In numbers less than one, zeros to the right of adecimal point that are to the left of the first nonzero digit are never significant. They are simply placeholders.5. In numbers less than one, the zero to the left of the decimal point is never significant. It is there tomake sure the decimal point is not overlooked.6. All zeros to the right of a decimal point and to the right of a nonzero digit are significant.438 g26.42 m1.7 cm506 dm10,050 mL900.43 kg4830 km60 g4830. L60.
