This Concept Map has information related to: Significant Digits, Computations Use Sig. Figs. such as Density, very small numbers shorthand way to write them is Scientific Notation, Lab Measurement and Precision involves Recording uncertainty in measurements, All measurements because of limitations on how precise the devices are that the readings are taken from. involves understanding Lab Measurement and Precision, Lab Measurement and Precision involves length, Significant Digits involve understanding Count Significant Digits, doing the computations with non-exact constants you will carry 1 extra digit more than the least number of digits in the least exact measurement., not have any more significant digits than the least exact measurement. involves understanding Count Significant Digits, leading zeroes are NEVER significant such as .000347 has 3 significant digits., Computations Use Sig. Figs. remember The use of significant digits does not improve the accuracy of our results. It just keeps us from claiming more precision than is justified by the measurements we used in the computation.
